I would be in favor of using series data in preference to any tags.
I've been implementing the code to use Series name as the iTunes/iBooks Category. The good news is that it works fine under OSX; the bad news is that it doesn't work under Windows.
Unfortunately, this is a limitation of the iTunes automation interface.
I'll leave the code in place with the hope that improvements in the automation interface are on the way.
Edit: I'm now rewriting the metadata when sending epubs to the iDevice, so I'm simply deleting the tags in the epub if a Series name is present. That allows the Series name to be used as the Category.
