BTW, I used a combination of revision IDs and
timestamps, because you
told me the revision IDs can get out of order through
deleting/undeleting revisions, and I wanted them in correct order no
matter what.
You should use IDs (and never timestamps) for purposes of uniquely
identifying a row, not for sorting. You should use timestamps (and never
IDs) for sorting purposes, and never for unique identification. You
shouldn't ever need to use a combination of both for a single purpose.
