Сортировка в битрикс

Есть сайт, на нём раздел с каталогом товаров, у товаров (элементов инфоблока) есть свойство PRICE (их цена), сейчас при открытии каталога товары выводятся не упорядочено, а мне нужно, чтобы они выводились по возрастанию цены.

Вот код странички, на которую добавлен компонент:

<?
require($_SERVER["DOCUMENT_ROOT"] . "/bitrix/header.php");
$APPLICATION->SetTitle("Каталог");
?>
<div class="main">

А вот код самого компонента, который обрабатывает данные и выводит их на страницу:
