Yes, you need ':exports results' as well as ':results latex'. The
':results latex' is necessary to specify that the *result* of the block
is latex code. The ':exports results' is necessary in order to tell it
only to include the result in the export product.

OK, so I think what you want is that the results are

(a) latex code, and
(b) in a box, set apart as different from the main text

Well, org-babel doesn't do anything like that with latex results by
default, so you'd have to do it yourself. How about defining a source
block function which does the job of putting your latex results in a
box, and calling it with #+lob ? The following exports to latex with the
results in a red box. (Please pull the latest org-mode as this required
a change that I've just made.)

--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \usepackage{color}

* Simple Test of org-babel
#+srcname: test()
#+begin_src python :exports none
  a = 1
  b = 2
  c = a+b
  "This is a Test: if a =" + str(a) + " and b = " + str(b) + " then a + b = " + 
str(c) + " right ?!" 
#+end_src

#+lob: putinbox(body=test()) :results latex :exports results

* Library code
  This could go in a separate file, as long as the file is added to the
  Library of Babel.
#+srcname: putinbox(body)
#+begin_src latex :exports none
\colorbox{red}{
body
}
#+end_src

tangle
