Result.ABORTED is not supported by DefaultStatusResultSource. I've tried to implement a fix here https://github.com/jenkinsci/github-plugin/pull/133. However, it doesn't appear that Result.ABORTED is going to work properly with the current isBetterThanOrEqual logic because ABORTED has the greatest value.

As a general note, I'm also confused why this isBetterThanOrEqualTo logic was used in the first place. It seems like a mapping of Result to GHCommitStatus would suffice.
