No, it doesn't. Feel free to browse the package or examine the app binary. It does use WebServicesCore, which is an entirely different framework for XML-RPC stuff. That basically means that the app can talk to a specialized web app without a browser interface.
iTunes does link to the rather primitive HTMLLib in Carbon, so I suppose they could replace that with WebCore in the future if the situation demanded it.
