The reason Ridley Scott deleted the scene was because of the tension of Ripley being completely alone, running through the big ship. Scott didn't want that tension broken with this scene so he cut it out of the final release. Makes sense to me because the tension of Ripley being completely alone, trying to make her way to the shuttle and being restricted by the time she has before the ship explodes is all very intense.
I was into Alan Dean Foster at the time too, he did a bunch of Star Trek books and a ton of other movie books like Outland, Black Hole, clash of the Titans etc... I still have all my paperbacks of the big blockbuster Sci-fi movies of the 70's and early 80's. I can't part with them for some reason.
