If you're really writing the contraint as (age ?age&>16), then that's
actually the problem right there; that's not the right syntax. You're
asking if ?age is the atom ">16", which it's not, of course. To call a
function in a constraint, you have to write (age ?age&:(> ?age 16)),
using the LISP prefix syntax for function calls.
Given that you've written the constraint properly, the < function will
automatically interpret the String "11" as the number 11.
