You can't really address screens that way; a screen holds a workspace, and
workspaces are addressable.  You can determine the workspace currently on a
screen, though, and use that.  Alternately you could use IndependentScreens
which effectively gives each screen its own set of workspaces, which change
in concert across all screens.

You *can* have conditional ManageHooks, using ExtensibleState.  I suspect
it's easier to use something in the same vein as FloatNext, though (but
that would mean remembering to activate it before creating each window).

I am tempted to say this is the wrong solution, though.  Looking at it from
a higher level, I think what you really want is IndependentScreens +
TopicSpaces; you would then be able to arrange that, in a given topicspace,
 emacs always opens on a particular screen.  (I don't know how well those
two compose, though.)
