I think so.

It has to be more sophisticated than this to minimize (heuristically
of course) sizes of diffs between versions. Sort by element type first
(rectangles, lines, text, pins...) and then by some part of the content:
text for text elements, certainly not location, this will automatically
sort attributes by name, but not by the value, however you may want
to classify text between attributes and random text.

Sort the pins by pinnumber (or pinseq, since pinnumber may change between
packages for the same chip) attribute. 

For other elements I have no idea. However, typically a symbol only has one box, 
(or very few) the the sorting on the B tag should be sufficient, and these are 
heuristics after all.
