Solution looks something like this:
<?php namespace fastPanel\Mvc;
use Phalcon\Mvc\Router\Annotations;
/**
 * Class Router
 *
 * Expansion of standard class annotations router.
 *
 * @package fastPanel\Mvc
 * @version 1.0.0
 */
class Router extends Annotations {
  /**
   * Set all routes.
   *
   * @param array $routes
   */
  public function setRoutes(array $routes) {
    $this->_routes = $routes;
  }
}
/* End of file Router.php */
/* Reordering routes. */
    $manager->attach('router:beforeCheckRoutes', function ($event, \fastPanel\Mvc\Router $router) {
      /* Route list to move. */
      $moveRoutes = [
        'Front:Abc:NamedPage:Locale',
        'Front:Abc:NamedPage'
      ];
      foreach ($moveRoutes as $route) {
        /* Find target route. */
        $namedRoute = $router->getRouteByName($route);
        if ($namedRoute) {
          /* Get all routes. */
          $routes = $router->getRoutes();
          /* Move target route. */
          \fastPanel\Helpers\Arrays::moveAsFirst($routes, $namedRoute->getRouteId());
          /* Set routes in new orders. */
          $router->setRoutes($routes);
        }
      }
    });
