you output vrbcatcodes strings while you test using ctx catcodesn

of course i'd use lua for all of it:

\startluacode
     local user  = ""
     local users = {
         ["oasi"] = 1,
     }
     function document.CheckUser()
         user = os.resultof("whoami")
         context.verbatim(user)
     end

     function document.UserNumber(name)
         context.verbatim(users[name or user] or 0)
     end
\stopluacode

\def\CheckUser {\ctxlua{document.CheckUser ()}}
\def\UserNumber{\ctxlua{document.UserNumber()}}

\starttext
This is user \CheckUser\ with number \UserNumber.
\stoptext
