It's usually a mistake to try to tune at this level. The tf/idf calculations _already_ take into account the field length (measured in tokens) when scoring. Matches on shorter fields add more to the score than matches on longer fields, which seems to be what you're looking for.
That said, the length of the field is encoded and loses some precision in order to save space (although I believe if memory serves you can use higher precision lately). So Solr/Lucene will tend to think most fields with, say, less n tokens are all the same length.... Very often, people spend lots of time chasing this down in artificial test cases only to discover that when looking at real data, the tweaking is unnecessary. So I'm not really giving you any guidance to do what you asked, rather I'm suggesting that you don't even try :)..
