Yes, that's true, but I don't think 1-2 characters is a big deal (except maybe as a simple tiebreaker). I believe I added the rounding to make the scores more pleasant to look at when DEBUG_SCORES is on (not a valid reason, admittedly).

I actually just confirmed that I can eliminate the DEDUCTION_FOR_LENGTH entirely right now and the tests still pass. I think this parameter has become less important after the other scoring tweaks.
