Hello, Abe22!
Sorry, I'm not with my Abe's Oddysee game right now, so I can't check it out to tell you the screen number of the third secret of Scrabania Temple, but I can describe you the level, I hope you find it.
Third secret. Its in a level where Abe start in an upper ledge and a scrab is waking just below him. He has to go left one screen, running away from the scrab, then go up, then go left.
In this screen, there is a flint lock. Roll left and you will find the third secret area.
Looking at this picture, I think its the first door in the lower right corner of the temple.
