Why is it a privilege to view vote counts? and its answer explains why seeing vote counts is a privilege (query cost + possibility for newbies to mess with votes).
Not allowing everyone to see these counts makes sense, but why is it so hard to get it?
You only have to make half of these points to have access to reviewing queues and I think that reviewing activity requires significant experience on SO, in order to do it right.
From my point of view, seeing vote counts is important because an answer with 50-47 clearly looks more problematic than one with 3-0.
Why was seeing vote counts set so high compared to other privileges (e.g. downvoting, accessing some review queues)?
