Put it inside the vbox and use \llap instead of \rlap.

\vbox{...\noindent\llap{1.2\ \ \ }\strut #...

(Actually, for a TOC it is better to use paragraph parameters and no
boxes or alignments. Then you have to pre-measure your page numbers
and section numbers, but that is inevitable even with halign because
you have to set the \hsize.)
