That's because numbers are not allowed in entities, except for a few
exceptions:

  "\\\\\\(there4\\|sup[123]\\|frac[13][24]\\|[a-zA-Z]+\\)\\($\\|{}\\|[^[:alpha:]]\\)"

Note that this regexp also matches LaTeX commands.

One seducing idea would be to drop support for such commands (I'm _not_
talking about math environments and snippets, but about commands like
\hfill{} or \bigskip{}). After all, if you want to write raw LaTeX in an
Org buffer, you can always use #+LATEX: or @@latex:...@@ like with any
other back-end. I see no compelling reason to keep this convenience if
it gets in the way.

It would speed-up a bit entities matching, and would allow for a relaxed
regexp (i.e. a regexp built upon already defined entities).


Regards,
