If you're currently in the viewport, you can access the cannoscalevalue variable.
If not, then it's more complicated and involves examining dictionaries, xdictionaries and
xrecords. You can cheat by making that viewport current via code and then check the noted
variable.

Not the VP scale:
(/ (cdr (assoc 45 xx)) (cdr (assoc 41 xx)))
The Anno Scale?
