Vote Up Down for comment needs to provide votes as comment views field

My goal was to use VUD to allow users to rate comments and then sort comments by their vote total.

I enabled voting then went about doing the sorting.

I was unable to modify the comment listing to order by votes (I'll create a separate issue for that) so I thought I'd use a comment view. However, the total votes a comment has received is not an available field for the views ordering.
