Thanks for the pointer (it's actually section 12.8.4 in my version of
Emacs/Org).  I now have

  #+LATEX_header: \newcommand{\mytick}{\color{green}{\tiny{(HPC-Kunden)}}}
  ...
     - Physik @@latex:{\only<2->\mytick}@@
     - @@latex:{\only<1>{Rechtswissenschaft}}@@ @@latex:{\only<2>{\color{red}{Rechtswissenschaft}}}@@

which does what I want.

I was wondering, however, whether there is a more compact way to do the
second line, i.e. without having to repeat the text for which I want to
change the colour.

Cheers,

Loris
