Shamelessly stolen from Larisa: What's Your Cheerscore?
How do you want to run this instance?
Rank by order of importance:
Learning the pulls
Learning the bosses
Fast: While obviously no one wants an instance taking ten minutes per pull as people go afk or a healer drinking every other mob. Chain-pulling; the paladin will cry if DP falls off.
Social: You're not in random PUGs to make friends, but why not be human and talk a bit? We're not the guys in Resevoir Dogs, we can talk. But I still don't want to know your name.
Kill everything: Maybe you want rep, XP, trash drops, or you're just a sociopath.
Explore: This means you're going to be going a little slower to look around, do some extra pulls, pick up quest items, and perhaps admire the art that the instances are.
Learning the pulls: This player is new, probably a new tank, and just needs some time to figure out what to pull, where pats are, where LoS obstacles are and when to use them. This will not be fast.
Learning the bosses: You might wipe on a boss. Or you might learn a new strat and be amazed.
Note that scores initially are nominative, not ordinal: in other words, they describe rather than rank. With some digging you could see how scores match up; so people with the same 1 and 2, or switched 1,2,3 might fit well together.
What would you add? And what's your score?

I noticed that the order in which I thought of these roughly matches the order of importance.
