One thing you haven't considered is the condition of the flex lines from the frame to the hubs. Flex hoses have a habit of deteriorating from the indside, with no evidence of problems from the outside of the hose. A restricted line on the left, for instance, will allow pressure to go to the right wheel cylinder first, allowing a pull to the right. In some cases, the pressure will get trapped downstream of the hose, giving a pull to the opposite direction when the brake pedal is released and pressure stays in the wheel cylinder on the other side. One quick way to check for a restricted line is to have someone step on the brake, then release it, and check for a wheel that takes a while to turn freely. To distinguish between a bad hose and a sticky wheel cylinder, open the bleeder screw quickly after the brake is released. If you get a squirt of fluid, the hose is the problem.
Edit: Yes, getting primary and secondary shoes reversed on one wheel will cause the brakes to pull toward the side with the brakes assembled properly.
