Hi John,
You don't have to worry about deleting old PA scores when rerunning historical collection jobs, as ServiceNow will delete old score for those dates (please see image below).
IMPORTANT: Please be advised that running (or rerunning) historical jobs comes at a cost. Not every indicator will collect data correctly when running retroactively (e.g. indicators of number of records not updated in the last X days). Also, breakdowns on fields that would have changed (e.g. assignment group, state) since the retroactive date will also collect an incorrect score (scores will reflect the current database value for that field instead of the value of that field at the retroactive date). Think twice before dropping old scores collected correctly through daily jobs and replacing them with new scores collected through historical jobs.
