title: Sort products by DESC order in Woocommerce
body: <p>I wrote this code in <code>functions.php</code> file of my active theme:</p>
  
  <pre><code>    add_filter( 'woocommerce_get_catalog_ordering_args', 
      'custom_woocommerce_get_catalog_ordering_args' );
      function custom_woocommerce_get_catalog_ordering_args( $args ) {
       $orderby_value = isset( $_GET['orderby'] ) ? woocommerce_clean( $_GET['orderby'] ) : apply_filters( 'woocommerce_default_catalog_orderby', get_option( 'woocommerce_default_catalog_orderby' ) );
      if ( 'random_list' == $orderby_value ) {
          $args['orderby'] = 'date';
          $args['order'] = 'desc';
          $args['meta_key'] = '';
      }
      return $args;
  }
  add_filter( 'woocommerce_default_catalog_orderby_options', 'custom_woocommerce_catalog_orderby' );
  add_filter( 'woocommerce_catalog_orderby', 'custom_woocommerce_catalog_orderby' );
  function custom_woocommerce_catalog_orderby( $sortby ) {
      $sortby['random_list'] = 'DESC SORT';
      return $sortby;
  }
  </code></pre>
  
  <p>I am trying to sort products by Desc, but products still sorting by default <em>(ASC)</em>. </p>
