On my setup, HIGH means the relay is off. Im using one of those 8 channel arduino style relay boards... it's negatively triggered. When I initially setup a prototype rig on a breadboard, with 3 LED's instead of relays, I did not get this phenomenon. I could read pins and the LED's would stay on. Now, with the relay board, everytime tasker commands a pin read, the relay turns off. It is clear the state is staying "LOW" (relay supposed to be on) because i can send a "TOGGLE" command and the relay stays off. When I send another "TOGGLE" command, then the relay finally turns back on. It's very consistent, but I'm not sure what's causing it.
