So you mean sort the "mailbox" by category? Or sort the category list? the category list seems to sort itself by "most used". You can indeed sort the mailbox by category, but the only way to get the categories to sort in any particular way would be to name them so that they would sort - so perhaps "1 - my favorite category" so it would sort to the top.
