Nope.  The idea is simply to take someone's grades and translate them into 
a ranked ordering.  So if I give Joe an A, Bob and Sally B's, and Frank a 
D, my ballot becomes:

1) Joe
2) Bob and Sally
3) Frank

The result would be the same if I gave Joe a C, Frank an F, and left Bob 
and Sally unranked (implicitly an "E").  Only relative grade matters.

The rationale to use grades to simplify the decision process and prevent 
confusion by the voter.  With numbered rankings, some folks might think a 
"10" is the best and a "1" is the worst, and vice versa.  It's much harder 
to make that mistake with letter grades, at least in the United States.

Note: it's true that this approach no longer allows strict ordering once 
you have more than six alternatives.  This doesn't bother me at all, but 
for those that it does bother, I'd note that adding plusses and minuses can 
triple the number of slots.
