Could you please give more details? For instance, show what the driver
returns and explain what you think it should return.

What is the "per-network" value, and how is it relevant to the driver?

That's basically what the driver returns, although this value can get
corrupted due to conversions to unsigned char.

Where does this come from?

Could you please elaborate? Is it the kernel driver or some kind of
"userspace driver for nm-tool"?

I don't understand this explanation. I think if anyone has a problem
with Orinoco driver, it should be reported directly to this list, and it
should be described without irrelevant details.
Note that I'm not saying that the signal data is correct (in fact, lots
of work is needed to calibrate it), but I don't think you made a good
case here.
I'm not going to check userspace software other than wireless tools for
compatibility with the driver. If wireless tools can work with the
driver, then other software should also be able to. If you think
otherwise, I'd like to hear detailed arguments.
