Since you had informed us that all EBU scoring computers had updated versions of both the Orange & White books, I think it's reasonable for a TD to expect to be able to use those. Also worrying because my version is 225 pages of A4 which is quite long enough. Am I missing some? I misremembered - my version goes up to page 477, but that's because I reformatted it to A5 thinking I could staple it into a book. Obviously far too thick for that, and even at only 239 pages of A4 too thick to go into a TD's pocket.
