OK. I just checked the source code again - it's (a little) more
sophisticated than I remembered. Indeed, if you have only the built-in
QtScript support, but no other plugins (lua, python), then this setting
is disabled, as it makes no sense. Besides, it could be potentially
dangerous if the user could change the setting without having any means
of checking the result (and, as a result, possibly forgetting over time
about the changes).
Anyway, I'm pretty sure now that the above-mentioned build simply
doesn't provide the lua and python plugins, and that that is the reason
the option is disabled.
