http://software.hixie.ch/utilities/js/live-dom-viewer/saved/1736 Webkit returns undefined, whereas IE, Gecko, and Opera all return an HTMLCollection. (IE returns an HTMLCollection with a tags() method, Gecko and Opera do not. The spec requires an HTMLAllCollection, which is the kind of collection that has a tags() method in the spec; in IE, all collections have a tags() method, and document.all is actually a regular HTMLCollection. We could change the spec here, e.g. to put tags() on all collections or to just forget about tags() on the subcollection here.)
I thought we had agreed to drop tags() everywhere except for the document.all collection. I guess the collection returned by document.all.foo wasn't discussed back then, though. Opera and Firefox don't support tags() there, which suggests it's not needed for compat, so maybe the spec should side with Opera/Firefox and return HTMLCollection instead of HTMLAllCollection.
