For those who are interested:

i found my mistake:

# create the reservation
setres -u martin -s +00:03:00 -d 00:05:00 TASKS==1
# this creates the reservation martin.0

# the following is not enough to bind a job to the reservation
qsub -W x=FLAGS:ADVRES:martin.0 testjob.cmd

# i had to provide the walltime argument with a time shorter (or equal)
# than the duration of the reservation:
qsub -l walltime=00:03:00 -W x=FLAGS:ADVRES:martin.0 testjob.cmd

then everything works.
