Doesn't it suck to type everything else in? It's much easier to tag and then have emplode populate its database from there. Then you also get track numbers.
Hopefully what you want (a solution to inputing track numbers after all your tracks have been synced) will be possible after scripting is supported. I believe Roger mentioned this feature in another thread - have no idea when it will be available to us though. I'm actually in need of some scripting support right now as well. I'm getting by using keyboard macros, but I don't think there's any way it would be possible to solve your problem easily this way (I can only easily access text fields and there's no field that I've seen that shows "position" in a copyable format).
