Try this in place of the Py script call:

<dtml-call expr="_.getitem(NewPlayerID).manage_addProperty('Score', 0.00, 
'float')">

If you need to add multiple properties, wrap them in a "with" tag:

<dtml-with expr="_.getitem(NewPlayerID)">
  <dtml-call expr="manage_addProperty(...)">
  <dtml-call expr="manage_addProperty(...)">
  <dtml-call expr="manage_addProperty(...)">
  ...
</dtml-with>
