LUA script help for bomb scoring

[damn it not again]

Okay I need some help. I have very very very limited knowledge on LUA. I'm trying to score bombs dropped on a specific target but I cannot get a return on this script. Where did I go wrong or do I just need to scrap it.

-- Define target point
local targetPoint = {
    x = 451519,
    y = 623,
    z = 897725
}

-- Bounding box size in meters
local delta = 30 -- +/- 30 meters

local targetZone = {
    x_min = targetPoint.x - delta,
    x_max = targetPoint.x + delta,
    y_min = targetPoint.y - delta,
    y_max = targetPoint.y + delta,
    z_min = targetPoint.z - delta,
    z_max = targetPoint.z + delta
}

local score = 0
local bombsTracked = {}

-- Function to check if position is within target zone
local function isWithinTargetZone(pos)
    return pos.x >= targetZone.x_min and pos.x <= targetZone.x_max and
           pos.y >= targetZone.y_min and pos.y <= targetZone.y_max and
           pos.z >= targetZone.z_min and pos.z <= targetZone.z_max
end

-- Event handler for bomb impact
local function onEvent(event)
    if event.id == world.event.S_EVENT_SHOT then
        local initiator = event.initiator
        if initiator and initiator:getTypeName() == "MK-82" then
            local pos = initiator:getPosition().p
            local bombID = initiator:getID()

            -- Avoid scoring multiple times for the same bomb
            if not bombsTracked[bombID] then
                bombsTracked[bombID] = true

                if isWithinTargetZone(pos) then
                    score = score + 100
                    trigger.action.outText(string.format("MK-82 #%d hit the target! Score: %d", bombID, score), 10)
                else
                    trigger.action.outText(string.format("MK-82 #%d missed.", bombID), 10)
                end
            end
        end
    end
end

-- Register event handler
world.addEventHandler({onEvent = onEvent})

S_EVENT_SHOT triggers when firing a weapon, not when it impacts. Dunno whether S_EVENT_HIT will trigger when a bomb hits the ground without damaging any units. Also unsure whether your use of addEventHandler() is correct. See here for an exemplary use of S_EVENT_HIT to detect (H)ARMs that hit a ship:
