Possible fix for the WP_DEBUG "doing it wrong" warning

I’m testing this code change, what do you think?
ceceppaml.php Version: 1.3.46 Line 999:

function enqueue_script_search() {
  wp_enqueue_script('ceceppa-search', WP_PLUGIN_URL . '/ceceppa-multilingua/js/ceceppa.search.js', array('jquery'));
}

change to:

function enqueue_script_search() {
  wp_enqueue_script('ceceppa-search', WP_PLUGIN_URL . '/ceceppa-multilingua/js/ceceppa.search.js', array('jquery'));
  $array = array('lang' => $this->_current_lang, 'form_class' => $this->_filter_form_class);
  wp_localize_script('ceceppa-search', 'cml_object', $array);
}

ceceppaml.php Version: 1.3.46 Line 2090:

if( $this->_filter_search ) {
  //For Fix Notice
  //add_action('wp_enqueue_scripts', array(&$this, 'enqueue_script_search')); //Non funziona :(
  $this->enqueue_script_search();

  $array = array('lang' => $this->_current_lang, 'form_class' => $this->_filter_form_class);
  wp_localize_script('ceceppa-search', 'cml_object', $array);
}

change to:

if( $this->_filter_search ) {
  add_action('wp_enqueue_scripts', array(&$this, 'enqueue_script_search'));
  add_action('admin_enqueue_scripts', array(&$this, 'enqueue_script_search'));
}

or even better:

static $script_search_enqueued = 0;
if( $this->_filter_search ) {
  if (! ($script_search_enqueued++)) {
    add_action('wp_enqueue_scripts', array(&$this, 'enqueue_script_search'));
    add_action('admin_enqueue_scripts', array(&$this, 'enqueue_script_search'));
  }
}
