It needs to be written AUC@TeX{} .  Maybe the toc code errouneously
strips the braces? ...  Oops.  In doc/macros.texi, we have

\global\let\savedTeX\TeX
\gdef\TeX#1{\savedTeX#1}

This would indeed cause this problem.  Maybe try

\gdef\TeX#{\savedTeX}

instead of the second line?  That would not strip but retain the braces.
It would inhibit kerning after @TeX{}, like when writing @TeX{}O, but I
don't think that should be a relevant problem.  Worth a try.
