I believe Lucene already does this, with the 'coord' factor in BooleanQuery, which is on by default (ie, if you just "new BooleanQuery()").
Ie your doc c will get a coord factor of 1.0, doc b gets 0.666..., doc a gets 0.3333. That said, if the term freq is high enough (ie doc a has nacho 4 times), that may give it a high enough score to overcome its coord disadvantage (I'm not sure).
