So you made the first sync while NoScript was NOT installed yet (installing NoScript still requires a browser restart, it will change after NSA merge later this year), and therefore imported everything from the cloud except NoScript's settings.
Then you restarted, so default NoScript settings were created which were the most recent across all your devices: on next automatic sync, these default settings overwrote the "older" ones on the other devices of yours. Mistery solved.
Bottom line: for everything go smoothly, you either need to have NoScript already installed (restart required) when you perform your first synchronization, or be prepared to do it manually.
Please let me know if I misinterpreted something in your timeline.
