The problem is that you need to "funnel" the player through your map. Make the player go down a set path and have things happen around him as he moves along. Your map has too many scientists standing around in one spot so the player (or in the case of this map where there's nothing to do, the "watcher") doesn't know where to go or what to look at.
I'm not saying maps should force a player down a rigid path, but in the case of using scripts, when you design your map you want to make sure that the player is at least in a position to see them, AND equally important is that he should know that he's supposed to be looking at them.
With all the scientists in such a small area, and no sense of purpose in the map, it's not hard to understand why no one noticed the scripts.
