I'm sure those who have wrote complex scripts would probably disagree with you.
Do you know what writing complex scripts in equally complex environments entails? I sure don't, therefore it makes me sufficiently unqualified to determine "meta levels" (whatever that means) for that skill.
Unless you are deeply familiar with both, i'm not sure how you can say one is higher then the other.
I hit the "reply" button to tell you that no, no amount of "complex scripting" is as mentally challenging as developing a Turing complete language.
But maybe you mean scripts as any program? In that case, I agree that developing things like, I don't know, database engines and file systems and such are equal in complexity to developing a language.
I suppose the only caveat is that those things are usually teams -- sometimes huge teams. A language is often a 1-man or small team effort.
