As Dimension Door, Teleport, and plane shift all use the same mechanic to cross space quickly, it makes little sense to have the results of that shift affect in-place spells differently.
Sorry, I should have been more comprehensive in my answer. This tends to be "stream of consciousness" stuff since it is an issue I'm thinking about at the moment, rather than rules that I've sat down and thought through carefully.
Basically, the above spells all work using the same mechanic in the standard Greyhawk and Forgotten Realms cosmology, but in different cosmologies there may be way-different explanations for how they work.
As you might guess from my online name, I'm heavily into different cosmologies from any of the standard ones (and Manual of the Planes is just such a stupendous resource for designing brand new cosmologies

My final thoughts on the B-S-T issue are not set in concrete, useful stuff has come up on the discussion thread I started for it and I don't need to have a solid explanation yet. It is quite possible that I'll concentrate on tackling the "scry" part of the equation rather than the "teleport" part.
