I've since updated the Sci|TE config as well, so I may as well post that:

Covers nearly all ZScript syntax, but not the std.zh functions. I intentionally omitted Item and Script, so that only the lowercase item and script would be caught as tokens, and highlighted.
I've considered shoving all the std.zh functions into the directives section, so that they can have unique highlighting styles.
I didn't do any preprocessor defs though. I'm kicking meself for not noticing Gleeok's preprocessor in the past. if I ever grabbed that, the memory of it has since fallen out of me ears.
