If I print the different hit score for each doc, they are the same.. but the secondary sorting still does not take affect. is it possible that even though the float returned to me and i print out, internally has even more precision and they are indeed not the same? I'm getting ready to edit the lucene source and recompile.. but I just wanted to make sure that this is indeed my problem.
How did you index your rank field? That has bearing on how sorting works. What are the values of the rank field like? Numeric?

Richard, thank you, but i would need the score to be changed inside lucene in order for the sort to work properly... my earlier questions was in regards to rounding the score internally in order to allow for a secondary sort to take hold when similar results... say to a precion of 0.## occur.
Thanks, Chris

score1 = ((float)(int(score*100+0.5)))/100.00
'score1' will equal 'score' rounded to the nearest 0.01.

Is there a way to generalize the score that lucene is comparing ? I.e.
round it off to say a precision of 0.## ? In order to make this sort
work better with 'duplicate' values? (by my terms... hits that have
scores within within a certain distance of eachother.)

I get the same results as I did with the score_sort only... no change
in the ordering of the rank is there... any ideas? It looks to me as
if it's completely ignoring it.
This is sorting first by score and then by your rank field. The rank
field sort only applies when the scores are the same. I suspect you're
getting different scores so you'd never see rank come into play.
Display the score and rank in your results to see for sure.
