Folding and Grain...

Here's your answer: your problem is twofold.

The thinner the paper, the lighter the score you must make. (Not "less wide", but less impression.) Remember that generally you are breaking the paper fibers somewhat when you score (or crease), even if it looks as if you are simply compressing them or re-forming them.

A sheet that has been baked in a digital machine will be more brittle and won't be very supple until it has absorbed some moisture. And even then it won't approach the suppleness of a sheet that never was baked.

So: Try to let the sheets re-humidify a bit and use the broadest score you can get away with, with the least pressure. If you can channel score to give 2 "hinges", do it.

As a general rule: 100# gloss book and lighter simply needs a nice, loose fold along the grain without any score at all. If you want a tight fold, that's where you'll get your problems.
