Could these be presented in recording date order?

Nope, if they were in recording order, then "Charlie X" (8/29/66) would be between "The Man Trap" (8/19) and "The Naked Time" (8/31). I think they must be grouped by composer, at least within each season. For season 1, counting the pilots, that'd be 4 by Courage, 6 by Steiner, and one each by Kaplan, Mullendore, and Fried. Since a couple of Steiner's scores were partial, maybe discs 3 & 4 will be Steiner and disc 5 will be the other guys.
