My guess is that \doifnunmberelse won't work since it's not only the
number hidden there, but also formatting, conversion, ... etc.

But I have no idea how to do it in some other way. You may take a look
at the following, but it has the side-effect that it will not only be
used in TOC, but also in text which is most probably not what you
want:

\def\mychapterlistnumber#1{\vbox{#1\crlf}}
\def\mysectionlistnumber#1{\emspace\emspace}
\def\mysectionlisttext#1{%
\setuplist[chapter][width=1em,numberstyle=bold,%
numbercommand=\mychapterlistnumber,textstyle=bold]
\setuplist[section][width=2em,numbercommand=\mysectionlistnumber,%
textcommand=\mysectionlisttext]

\unprotect

\setupsection
[\s!section-2]
[\v!appendix\c!conversion=appendixconversion,
\c!conversion=chapterconversion,]

\protect

\def\appendixconversion#1{Appendix #1}
\defineconversion[appendixconversion][\appendixconversion]

\def\chapterconversion#1{Chapter #1}
\defineconversion[chapterconversion][\chapterconversion]

\starttext
\startcolumns[n=2,distance=.3in,balance=no]
\bgroup
\placelist[chapter,section][criterium=all,alternative=b]
\egroup
\stopcolumns
\page
\chapter{Foo}
\section{Bar}
\input knuth
\startappendices
\chapter{Corge}
\section{Grault}
\input zapf
\stopappendices
\stoptext
