Apparently there's something very wierd happening with scoring of the prefix fuzzy searches. You don't mention what your locale is set to, but if you use a locale in which the decimal point is a comma, you may have to use a comma rather than a period for the prefix weight in search_algorithm. It may be that all prefix matches are getting a score of 0, so if there are no exact matches, it can't figure out the maximum score correctly. I'll look at the code to confirm this hunch, but do check your locale and maybe try changing the prefix weight.
