Not sure if I understand the problem. How can logger update have any
impact to the $PPID if this variable is generated by shell?

 $ logger --no-act --stderr --id=$PPID "this is message"
 <13>Oct 12 12:40:07 kzak[1562]: this is message
 $ logger --no-act --stderr --id=$PPID "this is message"

.. still the same number. It seems that the problem is your script
where is probably any fork/exec before logger call.

Maybe you need to save the PID at the begin of the script:

#!/bin/bash

REPORTED_PID=$$

... your script ...

logger --id=$REPORTED_PID "foo: blah"
