Default Surrogate key

In my package i need to implement surrogate key on sequence wise.any one can help.ASAP
Ex: custid product date
    100 pepsi 12/9/07
    101 coke 13/7/06
For this i generated surrogate key using the following code.
__________________________________________________ __________
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper

Public Class ScriptMain
    Inherits UserComponent

    'Declare a variable scoped to class ScriptMain
    Dim counter As Integer

    Public Sub New() 'This method gets called only once per execution
        'Initialise the variable
        counter = 0
    End Sub

    'This method gets called for each row in the InputBuffer
    Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
        'Increment the variable
        counter += 1

        'Output the value of the variable
        Row.Sk = counter
    End Sub

End Class
__________________________________________________ ____

for this the out put is:
sk id custid product date
  1 100 pepsi 12/9/07
  2 101 coke 13/7/06

It is ok.

But my data is like this.

custid product date
    100 pepsi 12/9/07
    101 coke 13/7/06
    100 Dye coke 10/1/08
    101 coke 10/1/08

I want out put like this

skid custid product date
  1 100 pepsi 12/9/07
  2 101 coke 13/7/06
  1 100 Dye coke 10/1/08
  2 101 coke 10/1/08

if the customerid is same it will generate same SKID.
