The order= mechanism doesn't seem to work for \definelist lists as opposed to the built-in ones, viz:

\definelist[chron]
\starttext

\placelist[section][order=title]

\section{Hans}
\writetolist[chron]{}{Hans}

\section{Peter}
\writetolist[chron]{}{Peter}

\section{Anton}
\writetolist[chron]{}{Anton}

\placelist[chron][criterium=all,order=title]
\stoptext
