We have never seen Snape award points to anyone.  We have, 
though, seen him take many points from Gryffindor that were not 
at all justifiable, and we have seen some instances when he was 
justified in taking some points, but took too many (compared to 
the same or similar offenses in other situations).

However, we have never seen him take a single point from any 
Slytherin, even when a Slytherin does the same thing for which he 
took points from Gryffindor (such as being late for class).

One must ask, how is it that Slytherin won so many House Cups? 
They are not brilliant scholars.  Nor are they all that good at 
Quidditch (if they were any good, they would not have to cheat so 
much).  The most plausible explanation is that Snape sees to it 
that they win by unjustifiably deducting points from other 
houses, and unjustifiably awarding points to his own house.
