Hm. You are expecting (12 10)?

The quote extends to the whole (parenthesized) expression, i.e.
the y is quoted too, in there, so it's the symbol y, so that
output is correct:
> #+RESULTS:

(That's Scheme, not Babel doing it). I don't know where you
want to go to, but perhaps try:
(list 12 y)
instead: this would make a list of whatever 12 evaluates to (this
would be 12) and y evaluates to (this would be 10).
Cheers
