^Well, there's no need to be so harsh about it. Nobody here had any intent to deceive or mislead. Probably what happened is that Huston did some arranging help for Courage, and either he misremembered how much work he'd done when asked about it two decades later, or what he said got distorted/misinterpreted in the course of being conveyed from Huston to my father to me. An honest misunderstanding, nothing more.
I'm curious to know more about your conclusion, though, since to my ear Courage's third-season scores have a distinctly different style from his pilot and first-season scores. I don't dispute that they're all by him, given what was reported about the third-season scores being written in his hand, but they do sound very different to me, so I'd like to hear your thoughts on the stylistic similarities you discern.
