Multiple-level sorting with the pure Muenchian method involves divining a key combination that is unique at each level of the key sort and then recombining this for each node being tested.
Personally, I find that sorting sub-groups is a lot easier using variables instead of using key tables.
You don't give enough data to write a quick test file, but here is the outline of the code structure:
I hope the above helps.

I've been stuck on the next problem for a few days now, eventhough the answer must be real simple ( I think), I cant figure it out.
