Did you enable DummyPowerManagement under Kernel?

No, I swapped your SSDT-PM with the one for my CPU, which is working in my build

You shouldn't do that. You need to generate your own SSDT-PM based on the OC guide. Sandy Bridge builds might need DummyPowerManagement enabled under Kernel if you would normally use NullCPUPowerManagement.kext or you will get a kernel panic on boot.

That’s exactly what I did! The build is working perfectly, including USB3, USB mapping, CPU PM, shutdown, restart and Sleep.
Only thing that is not is the “Bless” function neither via Emulated NVRAM nor with AllowSetDefault.

I have two SSD’s, one running 10.8.5 and one 10.13.6
I need to make High Sierra the default startup disk

Attached are my config.plist, nvram.plist and OpenCore debug log

I guess the problem is the highlighted part in the attached image.

Is there anything I can do?

small progress...

removed OpenRuntime.efi from UEFI drivers, both OS's seem unaffected and properly working, and OpenCore log is not showing errors anymore, but it still ignores the blessed partition, booting the first drive in the menu.

Any idea?
