Interesting, what I may do then before attempting any scoring system would be to aim for automatically gathering results with and without punctuation into a single list and then sorting on the current basis. So if the title is "Bridget Jones' Diary" get it to isbndn both "Bridget Jones Diary" and "Bridget Jones' Diary" and concatenate the results sets.
I've noticed similar things for initial style authors eg H G Wells vs H. G. Wells vs H. G Wells etc.
