Hi.

I also have such a problem with the size item of the styleobj. I created 
a symbol 'circle' (like in the mapfile reference) and add it to my 
'template' mapfile (containing the stuff I often use). When I add my 
point layer to this map and apply it to my new style with a specific 
size then my points are displayed the right size.

The way I see in mapscript is to create a symbolsetfile (texteditor?) 
and set the symbols to the mapobj from this file. In the normal mapfile 
you can have the symbols and the symbolsetfile under the mapobj but in 
the mapscript mapobj you only can have the symbolsetfile.

Perhaps there is another way with SLD but I never worked with that yet.

Norbert
