Don't know if it's useless for you now, but there are just flags you have to set for each. Just add these to your script:
Navel Rock:
setflag 0x101
setflag 0x84A
Birth Island:
setflag 0x100
setflag 0x84B
Now I don't remember if this is correct, I had lost everything in a HDD crash and just recently found a backup of my old ROM, and pulled this from the script because I saw your message. There was a list of all of the flags that I found a while back, if you can find that it will help a fuckton.
