China actually considered bringing Mongl Cyrillic to Inner Mongolia before the Sino-Soviet split

Easy answer! Because Arabic and Mongol scripts were too hard to learn for kids, so the Bolsheviks, being the internationalists that they were, initially changed them to Latin script, but the teachers complained that Latin script is too hard for kids, so they switched to the Cyrillic script. There was no cyrillisation of Georgian and Armenian because they were already easy enough, but there was Georgianisation of Abkhaz language, which was already written in Cyrillic.

Let me guess, the difference is called “Being good-looking”?
