I faced the same problem here. The only way I found to pass the "scope" parameter to facebook was coding my own OAuth client.

To do it, you must extend and implement the abstract methods of DotNetOpenAuth.AspNet.Clients.OAuth2Client.

On the GetServiceLoginUrl method you can add the scope parameter to the url. So, when you call the OAuthWebSecurity.VerifyAuthentication() method, the AuthenticationResult.UserName provides the user's email.

An example can be found here.

Good luck.
