this might seem like bikeshedding to many, but titles like these really bother me. The most popular orthography for a language is not the language itself. There are many many ways to write English or other languages outside of the Latin Alphabet and many ways to write their number system outside of our weird number system.
The most important aspect of a number system is just the base, but even that doesn't quite fit. If we look at the names of numbers in English (eleven, twelve, x-teen), there's clear evidence that a dozenol system was more natural. And in fact was probably more popular than base-10 which was only made official after the French revolution when they decided to go standards-crazy and decide a bunch of standards. There's rarely if ever something about a number system that ties it strongly to a "language" per se (let alone a particular orthography!)
