Resolution

1. Copy app/code/community/TBT/Rewards/Model/Sales/Order.php to app/code/local/TBT/Rewards/Model/Sales/Order.php so that you are not modifying core extension files.

2. Open app/code/local/TBT/Rewards/Model/Sales/Order.php, change line 50:

class TBT_Rewards_Model_Sales_Order extends Mage_Sales_Model_Order

class TBT_Rewards_Model_Sales_Order extends MDN_AdvancedStock_Model_Sales_Order

Please keep in mind that implementing any modifications to your MageRewards core code does void your support agreement because you're adding dependency to the other module.
