Looks like a bug to me. I can reproduce it too.

I tried using \( and \) as the inline math delimiters but that did not
work either: I got $ signs *inserted* and then latex complains about that:
foo.org:
--8<---------------cut here---------------start------------->8---
* Headline 1
** Headline 2, concerning \(\alpha\) and \(\beta\)
--8<---------------cut here---------------end--------------->8---
foo.tex (elided):
--8<---------------cut here---------------start------------->8---
...
\title{Headline 2, concerning \($\alpha$\) and \($\beta$\)}
...
--8<---------------cut here---------------end--------------->8---
