Does it work with Hans and Hant?  It looks like Hans and Hant are not listed in 
PropertyValueAliases.txt at
http://unicode.org/Public/UNIDATA/PropertyValueAliases.txt  (I'm not sure
whether it's intentional or a bug. I'll check with the Unicode folk). 

In the meantime, you can use  uscript_getCode(). See 


http://icu-project.org/apiref/icu4c/uscript_8h.html#ad7c87340add879032324be15...

It's a bit awkward to use  but not very much.

Strange, it seems like "Hans" and "Hant" are working with
u_getPropertyValueEnum.
