Honestly, all they going to look at is his Pilot score as long as he passed the rest of the test. . They use that number when calculating his PCSM score. The PCSM score is made up of the the pilot score, plus the TBAS test score along with any personal flying hours he may have. 88 is pretty good. My son had a 95 pilot score but Professional Flight is his major and had around 200 hours of flight time.. He did just ok on the rest of the scores. Everyone seems to emphasis that they do well on all of the parts, so I will too. Having said that, he got a pilot spot and the lower scores didnt seem to hurt him.
