Use Directive:

ListPointPlot3D[{{0, 0, 0}},
  PlotStyle -> Directive[PointSize[0.02], Hue[1]]]

or

ListPointPlot3D[{{0, 0, 0}},
  PlotStyle -> {Directive[PointSize[0.02], Hue[1]]}]

In v6, the plot routines allow a List of things to plot and a  
corresponding List of directives. If there's only one Directive, it  
applies to all the "things"; if there's a List of directives, the first  
applies to the first thing, second to the second thing, etc.

It's true that you only have one "thing" in your example (one list of  
points) and, from that, one might guess that you wanted to apply all the  
directives to it; but that isn't the syntax now.
