Finally figured out how to do this. After you've instantiated your NG surface object (and assuming it's the only one), you can set the scale_vertex_color property this way:

igetproperty, 'surface', scale_vertex_color=svc
svc[3] = clip
isetproperty, 'surface', scale_vertex_color=svc

The first arg to i(g|s)etproperty is a path-like string that qualifies the itools visualization object. If 'surface' isn't unique enough, I believe you can use igetid() somehow immediately after instantiating the NG surface to get the fully qualified string (looks something like: "/TOOLS/GRAPHIC/WINDOW/VIEW_1/VISUALIZATION LAYER/DATA SPACE/SURFACE").

Hope this helps someone else...
