Default [Q] Problems with Tasker recognizing orientation change?

I have an S5 which I use Tasker to recognize the phone being flipped face down to turn off the ringer, etc. I know there are other apps to do this, but since I use Tasker for other stuff I was hoping to continue. But, when the phone goes to sleep, it appears that Tasker can not recognize the phone being flipped. If I press the power button and flip, everything works fine, but not when the phone is asleep. Is there a setting I am missing to properly handle this? Any help is appreciated. BTW, the phone is rooted via Towelroot but running stock OS.
