I would suggest this one-line global UserTag:

    UserTag flycode Routine sub { return $Vend::Flypart }

Then [flycode] will yield an empty string if it is not a flypage,
and the item code if it is. Change your calc to:

 [calc]
	$Scratch->{page_arg} = $Tag->flycode();
	unless ($Scratch->{page_arg}) {
		$Scratch->{page_arg} = q{@@MV_PAGE@@};
	}
	return;
 [/calc]

Then it should work anywhere on the page.
