This little scripts help ordering WordPress categories by meta values - a thing which is not integrated into WordPress yet and which costs some time to integrate.

1. Create a meta value (or meta values) for categories to order by

To order categories by a meta value the first thing which we have to do is to create a custom category meta value to order these (this first script is adapted from bainternet.com, where it is demonstrated in more detail).  
//add extra fields to category edit form hook
add_action ( 'add_category_form', 'extra_category_fields');
add_action ( 'edit_category_form_fields', 'extra_category_fields');
//add extra fields to category edit form callback function
function extra_category_fields( $tag ) {    //check for existing featured ID
    $t_id = $tag->term_id;
    $cat_meta = get_option("category_$t_id");


2. Order the categories by the created meta value and display these

// get the categories
$categories = get_categories();
$sortar = array();
foreach($categories as $ct) {
	$term_id = $ct->term_id;
	$cat_meta = get_option( "category_$term_id");
uasort($sortar,create_function('$a,$b','return ($a[0]<=$b[0]) ? -1 : 1;'));
$ordered_categories = array();
foreach($sortar as $sor) {
foreach($ordered_categories as $oc) {
	// do whatever you want with your category objects
Have fun and be free to use these scripts. Improvement ideas are welcome.
