Score When Ship Bullet Hits An Enemy

Hi,
I have a small minigame I’m making, It consists of a top down view of a ship, and i am able to shoot enemy’s that fall down,(Kind of like Galaga) and I have run into a problem. I have a 3d Text Score system where you can run into 50 point power-ups (With the tag “50P”) and get points, but I need to know how to make it to where I can shoot my ships bullet which has the tag, “shipProjectile” and when it hits the enemy ships with the tag “Enemy” I need it to give me 100 points or so. Here is my script, I hope you may be able to revise it.

Thanks,
Brandon

My Script

var score = 0;
var score3DText : TextMesh;

function OnTriggerEnter( other : Collider ) {

if (other.tag == "50P") {
    score += 50;
    scoreText = "Score: " + score;
    Destroy(other.gameObject);
    score3DText.text = "Score: " + score.ToString();
 }
}

if i understood you correct

var score = 0;
var score3DText : TextMesh;

function OnTriggerEnter( other : Collider ) {

if (other.tag == "50P") {
    score += 50;
    scoreText = "Score: " + score;
    Destroy(other.gameObject);
    score3DText.text = "Score: " + score.ToString();
 }
else if (other.tag == "Enemy") {
    score += 100;
    scoreText = "Score: " + score;
    Destroy(other.gameObject);
    score3DText.text = "Score: " + score.ToString();
 }
}
