Is there a way to order categories?

add_filter( 'get_terms_args', 'wpse_53094_sort_get_terms_args', 10, 2 );
function wpse_53094_sort_get_terms_args( $args, $taxonomies ) 
{
    global $pagenow;
    if( !is_admin() || ('post.php' != $pagenow && 'post-new.php' != $pagenow) ) 
            return $args;

    $args['orderby'] = 'slug';
    $args['order'] = 'DESC';

    return $args;
}
