Hi Ramon, this was added January 5th 2006. There was a complaint from a non-HPC user that all his nodes with load "5" were marked red, although that load was absolutely normal for his deployment.
The value is set in conf.php (default 1.). The load is divided by it, resulting in a more apropriate coloring of the nodes for non-HPC loads. The issue was discussed on the list. $load_scale *is* set to 1 as default. This is in the 3.0.3 conf.php and was tested. Did you take conf.php from your 3.0.1 installation without checking for changes? One known bug is that the scaling is global and affects all nodes in a Grid. We should add a fixed per-node load-scale metric to be more flexible.
