Patches have been proposed in the past to enhance find_each this way,
but rejected as "wontfix": "This function is deliberately limited to
primary_key order because those values don't change. If you order by
title and manipulate the title in your block, you'll get nonsense /
repeated options back"

I don't know if that's a *good* reason or if it's just taking the easy
way out, but that was the reason ...
