Thanks! It worked for most of my casks, but not sublime text 3 because it uses the version format "Build 3XXX". Version needs to split on " " (space) and discard the non-numeric portion, but I'm not sure if this would break compatibility with other casks since version numbering is hardly consistent across apps.

If you are a user of maid, you could use this gist which was greatly inspired by this one.
