The most commonly placed on AD carries of the 3 as of right now are flat AD runes simply because it helps your last hitting. Minions have 0 armor until several minutes into the game (I think it's something like 15) and as a carry most exchanges in bot-lane are just poking one another.

It's a matter of personal pref and how you play her when it comes to MF though since she has a natural steroid to help with last hitting. I still go with Flat AD myself though since I max Q first for better harass, but if you max W feel free to go with Arm pen for stronger harass.

I've never done scaling AD but on paper it looks to be not as good as the other two simply because of how much they benefit you when you're at your weakest (aka early game.)
