At least Cocoa AppKit selects the foremost one just as we expect,
without the necessity of specifying the window that shall be shown.
That's the behavior of Emacs 22 Carbon+AppKit port and Emacs 23 Mac
port.  As far as I tested, many X11 window managers also behave like
this.  Only the NS port doesn't for some reason.

Given such situations, I'd think we should avoid touching the
platform-independent part (unless we have such a rather unusual
requirement like below).
