I'd use the moodle certificate extension so that the certificate issue is tracked on the LMS itself. This also means that obtaining a replacement is easier than having the user repeat the module.
Else use a small bit of script, check the total score against your criteria, if its -79% jump back to page 1, if 80+% go to the next page which is the certificate.
