I have no idea what's up with IE6/7 supporting this...it doesn't appear on MSDN
anywhere.

In any case,
http://svn.webkit.org/repository/webkit/trunk/WebCore/editing/EditorCommand.cpp
seems to limit the "unscript" command identifier to
"supportedFromMenuOrKeyBinding". So, this command identifier is useless for web
developers...
