I'm pretty sure that the problem here is that you're missing a &.
I think you have to write:
$LyX_Preamble .= &{$Geometry_Options{$op}}();
That is, $Geometry_Options{$op} is a reference to a subroutine, so you need
to &{...}() it to actually call the subroutine.

Actually, I'm a bit surprised that 560 works on that. Could it be that if
you try to stringify a code reference, Perl calls the sub with no arguments?
Or maybe the parentheses make Perl realize it's a sub.
