Using this:

#+begin_src org
  ## +BIND: org-export-latex-image-default-option ""
  #+LaTeX_HEADER: \usepackage{calc}

  * foo

  This is an inline image:=20
  #+LaTeX: \raisebox{-\height / 2}{\includegraphics{scomp3.png}}
  . It should not be scaled.
#+end_src

produces that for me:

#+begin_src latex
  This is an inline image:=20
  \raisebox{-\height / 2}{\includegraphics{scomp3.png}}
  . It should not be scaled.
#+end_src

So, it worked out-of-the-box.

You can try the dirty trick given by Carsten: adding `{}' in front of your
environment -- as "environments are only detected if they are the first thi=
ng
in a new line":

  #+LaTeX: {}\raisebox{-\height / 2}{
