In theory you'll never get any orphans unless "someone" does something bad.
   a) Something deletes MythTV recording files via the file system 
rather than using MythTV to delete them.
   b) Something edits the database directly.
   c) A HDD dies and you lose files as a result (in this case, running 
find_orphans.py is a good idea).

So, really, there's no reason to run it unless someone does bad things 
or you lose a HDD.

FWIW, I've never had any orphaned recording files (files without 
metadata in my database) and the only orphaned recording metadata (with 
missing files on the file system) I've ever had were due to losing files 
when HDDs fail.  I do, occasionally, get a few orphaned preview images, 
but their total size is always tiny compared to recordings and, we'll 
likely prevent that from occurring with changes coming for 0.26.
