The Reference Desk/Seven has the sonic screwdriver considerably before the TV movie?
From Tardis Wiki, the free Doctor Who reference

As the page on sonic screwdriver currently stands, it seems to imply that no Doctor Who media at all post-Survival introduced the sonic until the very end of the Seventh Doctor's life in TV: Doctor Who.
However, in at least the audio version of Love and War, (Part One, Track 8, 2:15) the Seventh Doctor opens a door to a Heavenite observatory buried underground with one. Is this a massive factual error and omission made by editors unfamiliar with the NAs, or did Jacqueline Rayner change how the scene played out in the adaptation for Big Finish?
