We are currently aware of an issue causing the Scroll of Resurrection to not be redeemable by players to reactivate accounts. We are currently working towards a resolution on this issue but do not have an estimated time for the completion of this.
As a note, Accounts which have been upgraded to Wrath of the Lich King are currently ineligible to receive a Scroll of Resurrection to reactivate their account. If any changes to the system are made to allow Lich King accounts access to the Scroll of Resurrection for a free trial period this information would be updated and noted in the Scroll of Resurrection FAQ.
