How fast can a user move something around? Unless you've got a
huge number of users simultaneously rearranging things, I'd say it
just isn't a big deal :-)

And that's exactly how I handle a similar situation with ~20 categories:
capture the DOM order of the elements and pass it by AJAX as a comma
separated list, which is exploded and used to update a table in the DB.
