I think the price is fine. Rememberr that this will be much more common on the Outer Planes and hence cheaper. I do like you suggested game mechanics, and would like to use them if we are unable to unearth any more data from the archives of the original planewalker site.
|Arborean rope is tough but flexible rope made from vines and similar foliage wound into a length. It's better quality than normal rope and not that much more expensive, so this durable piece of equipment is popular with those who can afford it.By: Christopher AllenImported from a previous version of Planewalker.com|

Granted it would be cheaper on the outer planes, but it really should be priced higher, if only for game balance.
Correct me if I'm wrong (I'm working from a 3.0 PH) but silk rope is 10gp. Admittedly this weighs more, but shouldn't it cost more than silk? 20gp? In terms of mechanics, I would venture +1 to use rope checks, 1 hardness, 3 hp/in, and a break DC of 26.
