Putting the right SOA-EDIT row in your domainmetadata table should take care of this. It is (very summarily) documented at http://doc.powerdns.com/domainmetadata.html

The documentation in SVN head is slightly more verbose, and it says:
                Available modes are: INCEPTION (which sets the SOA Serial to
                the current two-week signing period start in seconds since
                the UNIX epoch), INCEPTION-WEEK (number of weeks since the
                epoch), INCREMENT-WEEKS (which increments the serial with
                the number of weeks since the epoch), EPOCH (number of
                seconds since the epoch).  Finally, INCEPTION-EPOCH
                (available since 3.1) is special and sets the new SOA serial
                number to the maximum of the old SOA serial number, and age
                in seconds of the start of the current signing period.

INCEPTION-EPOCH is quite recent and does not work in 3.0

Kind regards,
