Remove all ratings from a SharePoint 2010 document library

Question

I have a SharePoint 2010 document library in which I have enabled ratings. During testing, several people rated a number of documents, and now I'd like to reset all the documents back to zero. However, I cannot find a way to reset the ratings.

Things I've tried:

Disable ratings and re-enable: The ratings are still there.

Disable ratings, wait 24 hours, and re-enable ratings: The ratings are still there.

Using PowerShell and the SocialRatingManager, attempt to reset the rating (http://www.sharemuch.com/2011/03/22/resetting-sharepoint-2010-social-rating-using-powershell/): The script runs, but nothing changes.

Using the script above, modified to try to do a Delete() method on the rating result: "Attempted to perform an unauthorized operation", even though I am running the SharePoint Powershell as Administrator, logged in as a site admin.

It seems like the last option should be the one to work, but I can't seem to get access to delete someone else's social ratings. Any input would be appreciated.

Social tag manager errors/not workings are usually related to rights, here is a very good guide how to resolve the issues http://www.sharepointpals.com/post/Programmatically-Manage-List-Items-Rating-with-Social-Rating-Manager-in-SharePoint-2013
