I confirm that this test doesn't work in Metacity (but works in Sawfish).

There's a comment in Gnome bugzilla
(http://bugzilla.gnome.org/show_bug.cgi?id=567528#c10) which gives
possible workaround. Appears that Metacity doesn't understand that
these three toplevels belong to the same application. But adding [wm
group $w .] after creating toplevel $w makes Metacity happy. The
attached modified test script works in Metacity too.

So, I wouldn't blaim Tk developers for this behavior. Though it'd
probably better to add a few words about [raise] behavior to raise
manpage. And certainly the severity of this bug isn't "important".

Cheers!
