You'll have to ask the person who's adding it. I don't know who that is at the moment, maybe Paul...?
I am writing the whole game "Cannonball" in Tier 1. The agenda I have suggests that someone from TGC will look at adding these in when the game is closer to completion.
The interpreters are written in native languages so adding support using the standard native commands does not seem impossible, just there isn't any documentation I've seen on how to do it. If I find out any more detail I'll let you know.
