You're probably right.

Unfortunately, your solution didn't work for me. It did, however, get me
thinking in the right direction. In case anyone is every crazy enough to
follow the same path, here's a much more simple solution that doesn't
even need \doifnumberelse:

\definehead[appendix][chapter]
\def\myappendixlistnumber#1{\vbox{Appendix #1\crlf}}
\def\mychapterlistnumber#1{\vbox{Chapter #1\crlf}}
\def\mysectionlistnumber#1{\emspace\emspace}
\def\mysectionlisttext#1{%
  \doifelse{#1}{Lab Tasks}{\hskip-1em\bf#1\hfilll}{#1}}
\setuplist[appendix][width=1em,numberstyle=bold,%
  numbercommand=\myappendixlistnumber,textstyle=bold]
\setuplist[chapter][width=1em,numberstyle=bold,%
  numbercommand=\mychapterlistnumber,textstyle=bold]
\setuplist[section][width=2em,numbercommand=\mysectionlistnumber,%
  textcommand=\mysectionlisttext]

\starttext
\bgroup{}Table of Contents\egroup\par
\startcolumns[n=2,distance=.3in,balance=no]
\bgroup
\placelist[chapter,appendix,section][criterium=all,alternative=b]
\egroup
\stopcolumns
