Not getting score for cluster function?

[Defender]

I need some help, do people get credit for scores using the clster in base legions?
My fuction below returns no score..

function StarburstClusterBomb::onExplode(%this, %obj, %position, %fade)
{
  if (!%obj.triggered)   
      return;
 
 
  // create the cluster bombs
  %objVelocity = %obj.getVelocity();
  for (%i = 0; %i < %this.clusterRingCount; %i++)
  {
      %angle = 0;
      %angleOffset = 6.28 / %this.clusterCount[%i];  // 6.28
      for (%j = 0; %j < %this.clusterCount[%i]; %j++)
      {
        %x = mSin(%angle);
        %y = mCos(%angle);
        %z = %this.clusterZVelocityRatio[%i];
        %velocity = VectorNormalize(%x SPC %y SPC %z);  //0.5                    //0.5                      //0.5

        //%randomVariance = VectorScale((getRandom() - 0.9) SPC (getRandom() - 0.9) SPC (getRandom() - 0.9), %this.clusterVelocityVariance[%i] * 2);

        %vec = "0 0 -1";
        %vector = "0 0 -1";
        %x = (getRandom() - 0.5) * 2 * 3.1415926 * 3.1415926;
        %y = (getRandom() - 0.5) * 2 * 3.1415926 * 3.1415926;
        %z = (getRandom() - 0.5) * 2 * 3.1415926 * 3.1415926;
        %mat = MatrixCreateFromEuler(%x @ " " @ %y @ " " @ %z);
        %vector = MatrixMulVector(%mat, %vec);

        %velocity = VectorAdd(%velocity, %vector);
        //%velocity = VectorAdd(%velocity, %randomVariance);

        %velocity = VectorScale(%velocity, %this.clusterVelocity[%i]);
        //%inheritedVelocity = VectorScale(%objVelocity, %this.clusterVelocityInheritance[%i]);
        %inheritedVelocity = VectorScale(%objVelocity, %vector[%i]);
        %velocity = VectorAdd(%velocity, %inheritedVelocity);
        //%velocity = VectorAdd(%velocity, %vector);
       
        //%p = new GrenadeProjectile()
        %p = new LinearProjectile()
        {
            datablock = %this.clusterProjectile[%i];
            initialVelocity = %velocity;
            initialPosition = %position;
            sourceObject = %obj.client.player;
            sourcePlayer = %obj.client;
            sourceSlot = %slot;
            client = %obj.client;
            stats = %obj.clusterStats[%i];
        };
       
        %p.setArmed(false);

        MissionCleanup.add(%p);
        %angle += %angleOffset;
       
%p.schedule(400, "Explode";  
       
 }
  }
