I think Lauper was heavily favored to win that year (and of course, she did) so it made sense to feature that category on the air. This year, Sting isn't the frontrunner for Score, though an upset is certainly possible, so the producers likely weren't interested in highlighting it.
I am disappointed book and score won't be televised. This year could easily mark the first year a musical solely written by women takes both writing trophies, and it would have been nice to see that aired.
I am a firm believer in serendipity- all the random pieces coming together in one wonderful moment, when suddenly you see what their purpose was all along.
