In the debug output is one error
-> Not adding sections: IndexError('list index out of range')
There is one thing in the output that is a bit strange. Here CMK will fetch the OIDs from your script. First it will fetch .1.3.6.1.3.1.0 (not .1.3.6.1.3.1.0.0) and than each seperate OID as requested by your script. Usually it sould only request the OIDs as configured in your script and not the base OIDs.

Can you try to remove the '0', # doorOpen OID?

I have used your SNMP walk as stored walk and tested with your script. Looks ok so far.
OMD[build]:~$ cmk -II rpz
discover
OMD[build]:~$ cmk rpz
check
if i tweak your script a bit, i get
OMD[build]:~$ cmk -v rpz

I am using CMK 2.2.0p5, but this sould make no diefference.
