add_filter( 'get_terms_args', 'wpse_53094_sort_get_terms_args', 10, 2 );
function wpse_53094_sort_get_terms_args( $args, $taxonomies )
if( !is_admin() || ('post.php' != $pagenow && 'post-new.php' != $pagenow) )
$args['orderby'] = 'slug';
$args['order'] = 'DESC';
The order may be
DESC, and the orderby can be:
description (it should, but didn't work so well for me, futher tests necessary)
Plugins of interest
(may we call those Plinterests?)

- Category Checklist Expander : expands the height of the category list, so no scrolling is needed
Category Checklist Tree : this one rebuilds the Category Meta Box, so you can modify its code for further styling/adapting the box - and here's a screenshot of what it does
Gecka Terms Ordering : creates an auxiliary table in the database (
wp_termmeta) to deal with the ordering. Has drag and drop capabilities.
