Incorrect Track Number being passed to control point

[simbun]

I need to retain disc number so I can run verify passes with CUETools. If I'm making global changes (like changing track number from 1-x per release to 1-x per disc, and thus filename conventions to [DiscNumber].[TrackNumber]....), before I perform a full backup I'll typically run a verify pass to make sure nothing has been screwed up e.g. forgot to change the filename references in the .cue sheets.
