Just beware that if you ever end up using a pagination gem (or rolling your
own) such that you get a single "page" of results using limit and
offset on
your back-end database, this''ll screw up any chance of your custom
sorting
working correctly. If you''ll never be using LIMIT and OFFSET SQL
clauses,
then this works great!
