I'm pretty sure the new line was recorded specifically for the SE. Just like Boba Fett's new voice and the new Emporer Hologram scene. If you compare Vader's voice to how he sounds in RotS, it's a match.
But "Alert My...." was done for the '97 edition, not the '04. It would have been easy to get the Jango Fett guy to record some lines for the '04 while he was around, but to fly in Jones for one line? Nah.
