Probably the easiest way to achieve this is to use your ranking as a
document specific boost (available in current trunk):
acts_as_ferret :fields => { ... }, :boost => :normalized_ranking
That way your ranking will directly affect the score Ferret calculates.
Useful values for boosts in the index are 0..255, you'll have to
experiment a bit to see what boosts work best for you.

what do you mean by ferret data? You may access the score Ferret
assigned to a specific result with the ferret_score method.
