I think you're argument is:

One has a reasonable expectation of seeing a list following a paren, so parens indicate the presence of a list.

I stipulate that this is a valid argument — true if it's premises are true — but I don't buy the premise.

The odds of seeing something other than a list after a paren is too great for it to be reasonable to expect to see a list following a paren.

Even with your made up number of 89%, that means one bug every 10 parens. That's a huge error rate! Much too great to use in teaching.
