That's because you're mixing braces and globbing. What happens first is:
f.*.{Atop,Bbot}.pnm → f.*.Atop.pnm f.*.Btop.pnm
then only globbing is performed.
You could have used globbing only, and the “o” flag to have a sorted
array in the first place:
PNMFILES=( f.*.(Atop|Bbot).pnm(on) )

PNMFILES2=${(on)PNMFILES}
