Custom Sort options for Catalog Dropdown

I created:
di.xml on app/code/Filter/Sorting/etc

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <type name="MagentoCatalogBlockProductProductListToolbar">
        <plugin name="Filter_Sorting::implementCustomSortOptions" type="FilterSortingPluginProductProductListToolbar" />
    </type>
</config>

for my Config.php on app/code/Filter/Sorting/Plugin:

<?php
namespace FilterSortingPluginModel;
 
class Config
{    
    public function afterGetAttributeUsedForSortByArray(MagentoCatalogModelConfig $catalogConfig, $options)
    {
        //Remove default sorting options
        unset($options['position']);
        unset($options['name']);
        unset($options['price']);
 
        //New sorting options
        $options['newest'] = __('New product');        
        $options['name'] = __('Name');        
        $options['price_desc'] = __('Price High to Low');
        $options['price_asc'] = __('Price Low to High');
        $options['name_asc'] = __('Title: A-Z');
        $options['name_desc'] = __('Title: Z-Z');
        $options['release_date'] = __('Release Date');
        $options['sales_popularity'] = __('Bestselling');
        $options['rating_summary'] = __('Top Rated');
        $options['reviews_count'] = __('Most Reviewed');
 
        return $options;
    }
}

and file Toolbar.php on app/code/Filter/Sorting/Product/ProductList:

<?php
namespace FilterSortingPluginProductProductList;
 
class Toolbar
{    
    public function aroundSetCollection(
        MagentoCatalogBlockProductProductListToolbar $toolbar,
        Closure $proceed,
        $collection
    ) {
        $this->_collection = $collection;
        $currentOrder = $toolbar->getCurrentOrder();
        $currentDirection = $toolbar->getCurrentDirection();
        $result = $proceed($collection);
 
        if ($currentOrder) {
            switch ($currentOrder) {
 
            case 'newest':
                if ($currentDirection == 'desc') {
                    $this->_collection->getSelect()->order('e.created_at ASC');
                } elseif ($currentDirection == 'asc') {
                    $this->_collection->getSelect()->order('e.created_at DESC');

                    $this->_collection->getSelect()->order('name DESC');
                }
            break;
 
            case 'price_desc':            
                if ($currentDirection == 'desc') {
                    $this->_collection->getSelect()->order('price ASC');

                }
            break;   

            case 'name_desc':
                if ($currentDirection == 'desc') {
                    $this->_collection->getSelect()->order('name DESC');
                } elseif ($currentDirection == 'asc') {
                    $this->_collection->getSelect()->order('name ASC');

                break;

            case 'rating_summary':
                $storeId = Mage::app()->getStore()->getId();
                $this->_collection->getSelect()->join('review_entity_summary',
                    'review_entity_summary.entity_pk_value=e.entity_id and review_entity_summary.store_id=' . $storeId,
                    ['rating' => 'ceiling(rating_summary/10)', 'reviews_count'])->order(['rating desc', 'reviews_count desc']);
                $this->_collection->setOrder('rating_summary', 'desc');

                    ['rating_summary', 'reviews_count'])->order(['reviews_count desc']);
                $this->_collection->setOrder('reviews_count', 'desc');
                break;


 
            default:        
                $this->_collection
                    ->setOrder($currentOrder, $currentDirection);
            break;
 
            }
        }        
        //var_dump($currentDirection);
        return $result;
    }
}

But latest switch case: rating_summary and reviews_count – not working, where i wrong? Thanks.
