How to make score increase score on touch?

I'm working on a simple ball-type game for Corona SDK, and I currently want the game's score to increase by one whenever a ball on screen is touched. Currently whenever it happens the text variable for score disappears and nothing else happens. How do I make the score increase? Here's my code:

function touchBall(event)
local ball = event.target
local score = 0;
scoreNum.text = score
scoreNum:setReferencePoint(display.CenterLeftReferencePoint);
score = score + 1
ball_h = 5

ball:applyLinearImpulse(0, -0.2, event.x, event.y)
ball_h = ball.y
if ball_h > 50 then
    gameover();
end
if event.target == "touch" then
    score = score + 1
    scoreNum.text = score
end

end

ball:addEventListener("touch", touchBall)
ball2:addEventListener("touch", touchBall)
ball3:addEventListener("touch", touchBall)



end

Create a Runtime Listener to maintain the score changes.

        local function runtimeListener( event )
           scoreNum.text=score
        end
        Runtime:addEventListener("enterFrame",runtimeListener)

Remove the line 15 and insert it as given above.

This makes the score keep on changing according to the touches..
