Round 9 score discrepancy

The official SANFL site has Centrals as scoring 20.6 (126) v West in round nine, but the Advertiser recorded it as 20.7 (127) and the scorers add up, and the latest version of the budget I have also has 20.7 (127) as the score.
Obviously has nothing to do with finals, but for purposes of accuracy. Can anyone shed any light on this matter?
