No, the line should be

\let \ifMT at inlist@ \iftrue


These easily mismatched conditionals is one reason why I favor using
constructions such as
  \IfXeTeXTF{<true code>}{<false code>}

If said construction doesn't exist, is is easily defined:
  \makeatletter
  \def\IfXeTeXTF{\ifxetex\expandafter\@firstoftwo\else\expandafter\@secondoftwo\fi}
  \makeatother

Also, the ifxetex manual tells you how to use ifxetex with the ifthen package.
