Just say "hey what's up?! Want to go out/grab coffee sometime?" I imagine if she has AS, then you won't need to beat around the bush too much. Good luck...
Mmm.... This is semi true, in the sense that aspie girls hate game playing, but then there's another side to it. Many of us have been taken advantage of and generally screwed around by men in the past, personally this has made me very guarded. I have *trust issues* and would want to get to know someone in a context in which I had other friends around before I made the decision to see them alone.
Of course, you've got that opportunity because of the party, which is great! I would just try and get talking to her for the longest possible time and hopefully there will be a bit of a spark between you, if you are similar people. You need to eventually bring the conversation around to something you just happen to be doing that you think she'd be interested in doing with you, ie. movie you'd like to see, gig you'd like to go to... whatever it is you do with your life. And invite her.
