[Plugin: My Category Order] use it manually

My client suddenly decided to rearrange his categories, and of course, neither ID nor NAME would get the required results.
So I installed My Category Order to get the job done.
But, since I didn’t use wp_list_categories() but cycled through the categories manually (needed descriptions, that’s why), I had to change some code to make use of the cool plugin. Old code:

<?php
global $wpdb;
$i=0;
$categories = $wpdb->get_results("SELECT $wpdb->terms.term_id AS id, name, description from $wpdb->terms INNER JOIN $wpdb->term_taxonomy ON $wpdb->terms.term_id = $wpdb->term_taxonomy.term_id WHERE parent = '$cat' ORDER BY name ASC");
foreach($categories as $category) :?>
	<h1><a href="?cat=<?php echo $category->id; ?>"><?php echo $category->name; ?></a></h1>
	<?php echo $category->description; ?>

<?php endforeach; ?>

New code:

<?php
global $wpdb;
$i=0;
$categories = $wpdb->get_results("SELECT $wpdb->terms.term_id AS id, name, description, term_order from $wpdb->terms INNER JOIN $wpdb->term_taxonomy ON $wpdb->terms.term_id = $wpdb->term_taxonomy.term_id WHERE parent = '$cat' ORDER BY term_order ASC");
foreach($categories as $category) :?>
	<h1><a href="?cat=<?php echo $category->id; ?>"><?php echo $category->name; ?></a></h1>
	<?php echo $category->description; ?>

<?php endforeach; ?>

Note: I’m using term_order to sort.
