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"

.. 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"
