You can pull out the individual readings for separate sensor entities
by using ipmitool sdr entity <entity>.<instance>.  

For example, for two CPUs in my system, I can get the sensor data from
CPU 1 with
ipmitool sdr entity 3.2
and CPU 2 with:
ipmitool sdr entity 3.3

You can use that to query the individual CPUs in your script.  That
way, if one of the CPUs goes away (which would be bad), your script
won't break because the number of fields and order of the fields has
changed.
