[Plugin : My Category Order] How to use without 'wp_list_categories'

Hello,

I am trying to find a way to do the following :

I have multiple departments, a team of persons, each attached to one dept. The number AND ORDER of departments are likely to evolve in the future.

I want to use categories for the departments : direction; sales; etc… all under the DEPARTMENTS category Wich means I need to be able to REORDER them if needed. I thought this plug in could offer what I wanted… but i can’t seem to be able to use it the way I want.

The team is currently shown on the DEPARTMENTS category ‘page’ using the following code :

global $ancestor;
$childcats = get_categories('child_of=' . $cat . '&hide_empty=1');
foreach ($childcats as $childcat) {
	echo '<h2>'.category_description($childcat->cat_ID).'</h2>';
  if (cat_is_ancestor_of($ancestor, $childcat->cat_ID) == false){
query_posts(array ( 'order' => 'asc', 'category__in' => array($childcat->cat_ID),'orderby' => 'meta_value', 'meta_key' => 'classement_equipe' ));
	if (have_posts()) : while (have_posts()) : the_post();
	echo '<div class="featured-thumbnail">'; the_post_thumbnail(); echo '</div>';
	the_content(__('[+]'));
	endwhile; else:
	echo 'error';
	endif;

When I change the category order, it doesnt affect this code… Any idea on how to do it ?

(Note that I am totally open to other ways to achieve this)

Thanks
PY.
