Try this
first assign the work sheet that you want to place the copy after. in this case sheet 2
objsheet = obj.Application.Workbooks(1).Worksheets('Sheet2')
this copys that first work sheet and palces it after sheet 2
obj.Application.Workbooks(1).Worksheets('Sheet1').copy(objsheet)


this is the test code I used for the references used above.
obj = createobject('excel.application')
obj.application.workbooks.open('E:\Proginfo\solutions\com\test.xls')
