i disagree. most airlines do see your results, they SHOULD be on your cv, many do not state it but require a certain mark - eg BA req 85%.
Put your self in the employers position, you get 1000 CV's for 5 jobs, how do u pick the best, obvious, you pick the person with the most qualifications, then narrow it down even more by seeing who out of these has the highest mark in the subjects.
I believe any one could pass the JAR exams at 75% with all the feedback tht is about, it takes knowledge AND UNDERSTANDING of the subject to get a pass mark in the 90's.
what you should be thinking of, is how can i make myself look better than the other guy up for this job, not can i make myself apear the same.
That said, i know of people who have got marks in the 90's and been turned down because they are not the write person. but like i said - anything to make yourself look that bit better.
good luck
