Just a reminder that the ID3 standard says that the field TRACK is a numerical string that allows the `/` as non-numerical character, the rest should be numbers.  
So, in a narrow sense, using letters like "A" and "B" would be invalid data, at least according to standard.  
MP3tag does not interpret the standard that strictly - but perhaps your player does.

And another question:  
perhaps this is a similar problem as described in this thread:
