Coin/Vehicle collision

I can't get the score to increase when I run over a coin in a vehicle (works fine on foot). Here is the collision in coins.cs:


function Gold::onCollision(%this,%obj,%col)
{
echo("Coin collision %this = " @ %this @ " %obj = " @ %obj @ " %col = " @ %col);
if (%col.getDataBlock().className $= Armor)

%col.client.Score += %this.scoreValue;
echo("score");
messageClient(%col.client, 'MsgItemPickup', '\c0You picked up %1 worth %2 points!!',
%this.pickupName, %this.scoreValue);
echo("picked up a coin");
Score.setValue(%col.client.Score); // NOTE: I typoed in my previous example, this is the way to call setValue.
%obj.respawn();
return;


echo("Coin Pickup failed");
}


As I said, this works fine. The following is the collision code in car.cs (it displays the 'You have picked up a coin' part but doesn't add the value to the score):


function WheeledVehicle::onCollision(%this,%obj,%col,%vec,%speed)
{
// Collision with other objects, including items
// need to set this up later
if (%col.getClassName() $= Coins) {
%obj.getMountNodeObject(0).pickup(%col);

%col.getMountNodeObject(0).client.Score += %this.scoreValue;
echo("score");
messageClient(%col.client, 'MsgItemPickup', '\c0You picked up %1 worth %2 points!!',
%this.pickupName, %this.scoreValue);
echo("picked up a coin");
Score.setValue(%col.getMountNodeObject(0).client.Score); // NOTE: I typoed in my previous example, this is the way to call setValue.
%obj.respawn();
return;

}

}


Any ideas?
