WordPress custom post type category order

I’m looking for a way to manually reorder the category list for custom post types,
are there any plug-ins that already do this?

I can probably code my own, but I’m not sure where to start, can you add custom fields to the categories that can be used to order them?

Anything to point me in the right direction would be great!

EDIT [resolved]

After a bit more digging I uncovered this:

http://wordpress.org/support/topic/plugin-my-category-order-custom-taxonomy-order-and-code-improvements

Which linked to this:

http://snipplr.com/view/48599/mycategoryorder-custom-taxonomy-mod/

and once you change line 51 to you custom taxonomy type it works like a charm, eg:

$tax = ($_GET['mytax'])? $_GET['mytax'] : 'category';

becomes

$tax = ($_GET['mytax'])? $_GET['mytax'] : 'my_custom_taxonomy';

works perfectly with ‘Types’ plugin linked by @Ajay Patel, cheers.
