I've found out some more since my last post in this thread...
As of firmware 1.0.3 it appears that TV shows are ordered by release date. Sadly the iTunes interface does not provide a way to update these values but there are 3rd party tools that can help.
Lostify apparently does the trick for Mac users, though I've no practical experience being stuck in the PC universe. PC users might like to try
Tagger....
Tagger needs a bit of effort to get working so for PC users I'll share my experience. The download is RAR compressed so first you need an unpacker for that - I plumped for
7-Zip. Tagger relies on a working Java RunTime Envionment, not just the browser plug-ins so I headed off to
java.sun.com for the *JDK 6 Update 3*. Once Tagger is up & running it's still not clear exactly how you are supposed to enter the date but further seaching revealed that it should be in the format
YYYY-MM-DD. The good news is, it works! I've only done one of my series so far but the episodes are now in the correct order. Tagger also includes options to change all sorts of other hidden attributes which aren't exposed in the iTunes interface, e.g. Podcast details, ratings etc.
