Externally, using texexec functionality. Something like this
works well enough, I guess (but I normally sort my stuff by
piping it through the unix sort command):


% This sorts the list contained in it's argument
\def\sortalphacommacommand#1%
   {\definesorting[listsort][listsorts]%
    \processcommacommand[#1]\listsort
    \def\sortedcommalist{}%
    \def\makesortedlist##1%
        {\doglobal\appendtocommalist{##1}\sortedcommalist}%
    \setupsorting[listsort][criterium=all,command=\makesortedlist]%
    \placelistoflistsorts
    \let#1\sortedcommalist}


\def\citylist{Londen,Berlijn,New York,Parijs,Amstelveen}

\sortalphacommacommand\citylist


Cheers, taco
