It appears that defcustom acts just like defvar and
custom-set-variables acts much like setq.
So the position of your load command, with respect to the
custom-set-variables section is unimportant.
Obviously the position of your call to foo-fn IS important.

In my .emacs nothing comes before custom-set-variables.
But I notice that if the section doesn't already exist
it gets added at the end rather than the beginning.
I question the logic behind that.  Especially considering
the existence of options like :require and :set-after which
make the need for anything before it unlikely.
At least it doesn't move if it's present so you can put it
where you want and it will stay.
