Incorrect Track Number being passed to control point

[simoncn]

The displayFormat setting only affects metadata sent to the control point and can't be used for sorting.

I think the simplest solution is for MinimServer to adjust track numbers on a disc only when any of the tagged track numbers on the disc is less than or equal to any of the track numbers (tagged or adjusted) on previous discs. This would preserve the current behaviour for users with 1..n track numbering on all discs and should also do what you want for your tagging scheme.
