Possible AHRS_ORIENTATION issue?

Hello,

for a narrow glider fuselage I need to install the APM2.5 in vertical orientation, GPS plug on top.

According to http://plane.ardupilot.com/wiki/arduplane-parameters/#Board_Orientation_AHRS_ORIENTATION I set AHRS_ORIENTATION to 19 (=Roll270)

But this doesn't work as expected.
Instead for 19 "Roll270" the parameter value 20 seems to work OK for this case.

Can it be that in the documentation between "17 Roll90Yaw45" and "18 Roll90Yaw135" a line with "Roll90Yaw90" is missing and the parameter numbers >= 18 shift up one number?

17Roll90Yaw45
18Roll90Yaw135
19Roll270
20Roll270Yaw45
21Roll270Yaw90
22Roll270Yaw136
23Pitch90
24Pitch270

Does anybody have an idea what AHRS_ORIENTATION parameter value I should set for:

Roll 270 (vertical, GPS plug on top) + Yaw 180 ( RC output pins to front)
