Correct, errAENoUserInteraction = -1713.

As you say, install a custom send proc into the AppleScript component.
Personally, I would have it send the event and sniff for errAENoUserInteraction
in the reply event, as third-party osaxen may run into the same problem and you
can't reasonably check for every possible event code beforehand. If an
errAENoUserInteraction is found, elevate the process then resend the event.
(Since it's already been responded to, I think it'll be safe to reuse the
original AppleEvent descriptor as-is without having to futz with obtaining a
new return ID.)
You can't install custom send procs via NSAppleScript. Can't recall offhand if
OSAKit allows it, otherwise you'll need to get down and dirty with the crusty
old Carbon OSA API. Which isn't all that hard, though OT for this list.
Alternatively, you could just be a pedant and insist anyone running AppleScript
targets dialog commands at System Events. This avoids the need to elevate your
GUI-less process in the first place, which also has side-effects such as
creating a menubar and Dock icon; that's what ASers do when using dialog
commands from osascript.

I would suggest taking further emails there - quieter and better suited to the
subject.
