I'm really replying to Peter here, not to Robert, but I cannot find
Peter's original mail.
You can change the underscore to e.g. a hyphen and get
,----
| \subsubsection{Experiment 1}
| \label{sec-1-1-1}
`----
in the LaTeX output, by changing it in org-exp.el around line 1300 (I
don't want this to end up on patchwork, so I am trying to camouflage it
by boxquoting it - I hope that works for hiding the patch from patchwork
and also gives you enough context to make the change if you so desire):
,----

What I don't know is if this change will break something, either in
the LaTeX exporter or in the other exporters. So you might test it
and report any problems and if there are no problems, maybe you can
suggest it as a permanent fix. In my limited experimentation, exporting
a simple org file to latex/pdf, text and html, I did not observe any
problems, but that does not mean that they don't exist.
