Answer:
Forward Iām heavy, but backwards Iām not.

I'm not really more than holes tied to more holes. I'm strong as good steel, though not as stiff as a pole.
Double my number, I'm less than a score. Half of my number is less than four. Add one to my double when bakers are near. Days of the week are still greater, I fear.
Both punishment and sweet reward, It will befall both fool and lord. It is a spiritual scoreboard, Your every deed it does record.
