versions: can Hazel distinguish manual- vs. auto-saved?

i recently updated to iWork '13. after some AppleScript struggles, i got my rule that makes PDF copies of any Pages documents in a folder working again.
the only issue is that the rule is, well, very trigger-happy now. every time i make any change in the file, Pages '13 auto-saves a version, updating the Date Modified attribute and firing the rule. i thought (incorrectly) that this would only happen when i explicitly saved a version. this information is kept somewhere — the Revert command knows the date and time of the last saved version — but the question is whether Hazel can access it and only fire the rule when i hit ⌘S.
