Coupon 100% off

As i mentioned in an earlier post i am working with halfoffdepot and i created a coupon that takes a 100% off the price. I am only using google checkout and paypal plugins since we have no gateway. The issue is that once they go through the checkout process the status of the order says created and i dont know how to get it to automatically go to a confirmed status when the coupon is put in since its a 100% off coupon.
