But it doesn't.

Run this a few times, and you'll see:

atable = Table[Random[Integer, {1, 10}], {50}, {3}];
colortable = Table[Random[Real, {0, 1}], {50}];
ScatterPlot3D[atable, PlotStyle -> ({PointSize[.05Random[]], RGBColor[#, 0,
           0]} & /@ colortable)]

All the points are the same size and color.
