David, if I hadn't given you a rep point already I'd sure do so now 
I also like it to take a step back every once in a while and think: wait, what is this?
It looks like normal, relatively fluent writing. If you hadn't been told that the script was unknown (and you're not a script expert) you wouldn't be able to tell at a glance that it may be "artificial".
By coincidence I was looking through my "initial thoughts" on the VM when I had just learned about it, written somewhere in the summer of 2015. I had two "blank canvas" ideas about the script:
1) The creator was a multilingual person who only mastered Latin and/or Greek script. He found that this script was not suitable to write in his second or third language, and he was not acquainted with any literary tradition in that language, only spoken. Hence he modified the script(s) he knew to make them suit his needs.
OR 2) The VM script is a simplified form of a foreign script, aimed to facilitate reading for those used to Latin or Greek script.
My current views are a bit more refined, but still along those lines. Because being easy to write is one thing, but for us, used to Latin script, it is also so easy to read! I wish all manuscripts were written as neatly as the VM
So basically, it might be the result of transcribing for practical reasons (expression or readability) rather than encoding for reasons of secrecy. I am certain of nothing, but the latter is low on my list of possibilities.
