Have you tried breadboarding this yet? I was working on a circuit that utilizes some of the same logic as yours (entirely different circuit though) and found that I was getting a 1.2-1.8vdc "floating" around the clear pins for the 74ls393n. I had to use a pull-down of about 1k to get rid of it. At approximately 1.3vdc on the clear pin, it was just enough to keep it in a constant reset state, and it wouldn't count. I would be interested to see if you ran into the same problem.
