Have a look here:

The list has been handed down to me through tradition (my teacher received it from her teacher and passed it on to me and so on – I see no reason to disagree so far).
I am not familiar with the Bartok edition, but I read somewhere in the forum that it is somehow idiossincratic and definitely not urtext (that is, it is packed with editorial performance directions – which to me says it is a very good edition to find out how Bartok played them, not necessarily a good edition on how Bach should be played, and as with any heavily edited edition certainly not authoritative in any sense). I would be very curious to see if his order of difficulty does indeed tally with the one I posted.
Best wishes,
Bernhard.
