This is the right place...

Yes it does, it takes the -context switch.  You can say:

AppleScript execute -context contextToken <Some Script Data>

And then the script will get executed in the context represented by
contextToken.  So the -- is necessary.  I guess we could be a little
fancier, and if there is ONLY one argument, then assume that that is script
data.  Tcl doesn't usually do this sort of second-guessing, however...
