Then don't use tags but metadata instead.

So use some metadata service.

Btw, the last CD I listened to has track numbers:
1 2 3 4 5 6 7 8 9a 9b 9c 9d.

Try to parse that numerically.

That's what I use, actually.

My player program uses it's own database, so I have actual meta-data
for use with my player.  Works fine.  Trying to force something even
slightly like this into the tag system will only create a mess.  And
anyway, it would be _waaaaaay_ to slow to try to extract the necessary
data for, say, "sort all of my tracks by title" from the Vorbis streams.
You really need to keep them in a nice database of some sort.

It's metadata about an album, not quick scribblings about one track.

It doesn't belong in the tags.
