Here is a implementation of uniform box scatter

scatter_box(activeDocument.selection, 100, 100);

function scatter_box(items, xoffset, yoffset){
    for(var i=0;i<items.length;i++){
       var oldpos = items[i].position;
       items[i].position= [oldpos[0]+Math.random()*xoffset-xoffset/2,
                           oldpos[1]+Math.random()*yoffset-yoffset/2];    
    }    
}

Here for uniform disc scatter.

scatter_disk(activeDocument.selection, 50);


function scatter_disk(items, rad){
    for(var i=0;i<items.length;i++){
       var oldpos = items[i].position;
       var r = Math.sqrt(Math.random()*rad*rad);
       var theta = Math.random()*2*Math.PI;
       items[i].position= [oldpos[0]+r*Math.sin(theta),
                           oldpos[1]+r*Math.cos(theta)];    
    }    
}

Obviously you could use other random distributions too.
