>PS: Currently I can get what I want with an apple script, instead of ps. I would like to have a way doing all these programmatically (I can use "ps" without actually using shell ps BTW via low level libraries) but anyway, looks like I will live with calling and parsing applescript output.

If I'm reading it correctly, it was the superuser link. It showed the [RDS][s]+ flags would indicate a foreground process:

R+
Rs+
D+
Ds+
S+
Ss+

The man pages may show additional detail. You might be able to coordinate the flags seen in a snapshot with what you see in the Apple tool and apply some filters to figure out what you're looking for.
