Are marketpress orders protected from being indexed by Google?

Hey guys,
I have a significant concern about the order status pages or the order tracking pages generated by Marketpress after a sale. Can these pages be found by Google? Because for example if my order number was 1a68d191c42f and I typed in

http://mysite/store/order-status/?order_id=1a68d191c42f

into the browser address bar I would get the order status for that order. Since the order status contains personably identifiable information (name, address, etc) I want to make sure that Google won't be indexing it. Thanks in advance!
