    global $wpsc_cart;
    if   ($total >= 0000 && $total < 1500) {
        return $discount->wpsc_cart_discount_number = '8';
    }   if ($total >= 1500 && $total < 3000) {
        return $discount->wpsc_cart_discount_number = '11';
    }   if ($total >= 3000 && $total < 7000) {
        return $discount->wpsc_cart_discount_number = '13';
    }  if ($total >= 7000 && $total < 10000) {
        return $discount->wpsc_cart_discount_number = '16';

}

When i call this function it keep returning only value of "8" and not other what is wrong here?

Based on the fact, that you do not have a local $total variable in your function, it is undefined. By the flexible error handling of PHP, this would be only a notice, not an error. An undefined value is treated as 0 when compared to integers, therefore the first condition will be always be true.
