If the Scroll of Resurrection is used on your son's account it will give him 10 days of credit which will allow him to play and access Burning Crusade content. If your son decides to continue playing and selects a subscription plan that subscription will not be applied until after the time on the account expires.
Note that if a game card is used that time is applied immediately and qualify the Recruiting account for whatever subscription benefits that are available.
