  Create two integer attributes called game.whichOne and game.randomNumber

  [repeat with a loop, Timer, rule condition, etc.]
       Change attribute game.whichOne to 0
       Change attribute game.whichOne to random(1,2)
       When attribute game.whichOne = 1
            Change attribute game.randomNumber to -100
       When attribute game.whichOne = 2
            Change attribute game.randomNumber to 100

  Or a simpler way:

  Change attribute game.randomNumber to (random(0,1) * 2 - 1) * 100

  You're welcome!

  Wish I could take credit. I Googled Lua random negative one or one since GameSalad is build in Lua. The first result was this:
