Github user gatorsmile commented on the pull request:
    cc @davies @cloud-fan . This PR is like an incremental patch with few lines of code changes.
I am not sure if the whole rewrite is worthy for resolving the above two issues only when
there exist the other operators between `Sort` and `Aggregate`? After all, users can manually
correct their query if they hit a resolution issue when missing attributes in Sort happen.
We already cover most of cases. : ) 
    Let me know if you want a whole rewrite or just an incremental fix. Thanks!
