Woocommerce how to sort by meta field with true and false values?

Question

WordPress

There is some code that adds a sort column to woo orders, but the sort doesn't work. in theory, the value of the order is true or false, and when you click on the title, sorting should work, but at the moment it sorts by date instead of the meta field. Where did I go wrong?!

function child_theme_mod_order_sortable_query($query) {
  if (!is_admin()) {
    return;
  }
  
  $orderby = $query->get('orderby');
  
  if ('custom_column_meta' == $orderby) {
    $query->set('meta_key','custom_column_meta');
    $query->set('orderby','meta_value');
    $query->set('order','ASC');
  }
}

add_action('pre_get_posts', 'child_theme_mod_order_sortable_query');

All code

// Добавление колонки в Заказы Woo
function child_theme_mod_order($columns) {
    $new_columns = array();
  
    foreach ($columns as $column_name => $column_info) {
        $new_columns[$column_name] = $column_info;
    
        if ($column_name === 'order_total') {
            $new_columns['custom_column'] = __('Custom:', 'child-theme');
        }
    }
  
    return $new_columns;
}

add_filter('manage_edit-shop_order_columns', 'child_theme_mod_order');


// Вывод
function child_theme_mod_order_content($column) {
  global $post;
  
  $order_id = $post->ID;
  
    if ($column === 'custom_column') {
        $order = wc_get_order($order_id);
    $order_meta = get_metadata('post', $order_id, 'custom_column_meta', true);
    
    if ($order_meta == 'true') {
      echo 'TRUE';
    } else {
      if ($order_meta == '') {
        add_metadata('post', $order_id, 'custom_column_meta', 'false', true);
      }
      
      update_metadata('post', $order_id, 'custom_column_meta', 'false');
      
      echo 'FALSE';
    }
    }
}
