Try
   (global-set-key [M-f3] (lambda () (interactive) (compare-windows t)))
or
   (global-set-key [?\e f3] (lambda () (interactive) (compare-windows t)))

The problem with your binding is that it uses the `escape' event.
This event is normally unbound and turned (via function-key-map) into an
ESC event (the "ASCII char 27 known as 'escape'") to which lots of
things are bound.  This mapping is because ESC is what is received in
a text terminal when you press the `escape' key, so some code somewhere
needs to "unify" the ESC char (from the tty) and the `escape' event
(from the GUI library).
