This appear to contradict your previous Unchecked Assertions, much less other data. Perhaps we're suffering from a lack of clarity about what sort of "script" we're speaking of; to wit, a writing system for the whole language, roughly as we understand it in the modern sense; or a restricted script used for sacred, decorative, and limited record-keeping purposes.
For the latter, an ideo/logographic system does indeed have some attractions. For the former, an alphabetic system (whether based on the Malkioni one or not) strikes me as bordering on being a "must". Needless to say, actually writing in such a manner will be far from common: it'd be rather a dangerously modern, citified, Foreign notion, which rural lawspeakers would be unlikely to use, much less anyone else.
