In fact, one of the things that Demonomicon talks about is that the process of becoming a Demon Lord involves several stages. One of those is the claiming of their Abyssal domain, which involves imposing their will on the reality around them, and the realm then changes to become their own. It might be a twisted, destructive realm of madness, but there is still a level of creation and imposed order there.
I still think the idea of a demon lord that designs out of instinct and madness is a perfectly serviceable explanation for the creation of a Clockwork Horror. I even realized we've actually seen things along those lines at least in past editions - Baphomet's 'Tower of Science' where he breeds monstrosities and experiments on living things.
The fact that he is doing 'science' doesn't mean he is going about it purely on logic and reason. They are twisted, tortured experiments - some born from cruelty alone, some to simply see, out of raw curiousity, what terrible result will be born from his work.
And if mad demonic science can be done with organic subjects, I see no reason it couldn't happen with clockwork subjects as well.
