Hi Torsten,
There are numerous syntactic issues in your example, try the attached
version which works. Additionally, I've pushed up a change which makes
the sbe macro somewhat more robust so that the quotes around 50 could
now be removed.

def score2mark(score, passscore):
marklist = [5, 4.3, 4, 3.7, 3.3, 3, 2.7 ,2.3, 2, 1.7, 1.3, 1]
step=(100-passscore)/(len(marklist)-1)
if score < passscore:
return marklist[0]
for mark in marklist[1:]:
if round(passscore) <= score <= round(passscore+step):
return mark
else:
passscore += step
return -1
return score2mark(score, passscore)
#+end_src
