POV 3.5 doesn't support that feature (I wonder when it got added to 
MegaPOV?), but you should still be able do it this way...

#declare imgFn = function {pigment {image_map {...}}}

density {average
    density_map {
        [1 function {imgFn(x, y, z).red}
            color_map {[0 rgb 0] [1 red 3]}]
        [1 function {imgFn(x, y, z).green}
            color_map {[0 rgb 0] [1 green 3]}]
        [1 function {imgFn(x, y, z).blue}
            color_map {[0 rgb 0] [1 blue 3]}]
    }
}
