Getting any point at all from that command is a bug.
The 3D matrix format provides implicit x,y values and one explicit z
value for each point.  There is no additional (4th) data column from 
which you can read a point size. 

I am guessing that you really were aiming for a 2D plot?
In that case the command you want is

gnuplot> plot '-' matrix using 1:2:3 with points pt 7 ps variable

This command does work here using gnuplot version 4.4, but
the exact size of the points will depend on the terminal type.
