A little off the top of my head, but IIRC, while you cannot have 
multiple finishes in a texture map of defined textures, I believe you 
can code up a texture map as:

texture_map {
     [0, pigment { pigm00 } finish { FinEmit }]
     [1, pigment { pigm01 } finish { FinPlain } ]
}

and get the differing finishes. I've never tried it with emission 
though, so if you do, let me know if it works. ;-)
