85% isn't bad and honestly, score means hardly anything in the long run. They really should just change those to pass/fail results. Is the guy who got a 90% REALLY that much more knowledgeable then the guy that got an 80%? Is the guy that scored higher going to be a better pilot? Not necessarily..
I scored worse on my PPL then I did my Instrument rating, but both were passing, so that's all I care about really.
My CFI told me he got a 70 something on his PPL, but you know what, he's an excellent pilot so, again, doesn't matter.
I wouldn't worry about the DPE drilling you on what you missed, he/she does have access to the results, but mine didn't drill me on the little items I missed, he was much more interested in determining if I was "master of the aircraft" during our flight.
You know what you missed and I'm sure you'll look it up just like I did, that takes all of a few minutes to correct, but all that time you are spending in the air actually APPLYING what you learned and adhering the the regulations is way more important (in my opinion).
Congrats on the pass, don't be bothered by it and enjoy the XC!
