Its adorable.. When you are like 12.. Try to find something to do in your area.. Like an art exhibition, music playing in a cafe, new waffle place opening.. Mention it and say: "You should come with me".. Don't worry about any scores.. Thats silly.. Her saying yes to the coffee is already a point for her.. I would give her 10 points for that..
But first i would suggest you scout your area on cafe's, bars, restaurants, cinemas., midgetgolf, etc. Cause, not trying to be mean, would you actually have a date idea if she came to you right now and said: "lets go out together tonight"?
-edit- maybe there is a after finals party...
