The specification says(http://dev.w3.org/html5/postmsg/#posting-messages) that the order of window.postMessage arguments is (message, targetOrigin, ports) while current WebKit implementation expects optional ports argument to go second i.e. (message, ports, targetOrigin). It was implemented this way in WebKit a couple of years ago(http://trac.webkit.org/changeset/32597/trunk/WebCore/bindings/js/JSDOMWindowCustom.cpp) so I'm not sure what we should do about this now when there may be some uses of that implementation.
