Who is right? Sql 2005 SSMS view of table or INFORMATION_SCHEMA?

Question

We scripted an old sql 2005 table under Management Studio and got this:
CREATE TABLE [dbo].[TestTable](
 [myId] [int] IDENTITY(1,1) NOT NULL,
 [Item_#] [char](8) NOT NULL, 
 [Count] [smallint] NOT NULL,
 [ProductName] [char](45) NOT NULL,
 [U_Item_#]  AS (upper([Item_#])),
Notice that U_Item_# computed column appears in the 5th ordinal position from the top.
Next I ran this query:
     select table_ProductName, column_ProductName, ordinal_position
     From INFORMATION_SCHEMA.COLUMNS
     where table_ProductName = 'TestTable'
Results returned:
table_Name      column_Name       ordinal_position
TestTable         myId                   1
TestTable         Item_#                2
TestTable         U_Item_#            3
TestTable         Count                   4
TestTable         ProductName        5
TestTable         U_ProductName     6
Notice that  U_Item_# is now in ordinal positon 3 which is not the same as that returned by the script.
Which  one is to be believed? (SSMS or INFORMATION_SCHEMA.COLUMNS)
TIA,

Answer 1

This is what I got in SQL Server 2014, same as CREATE TABLE:
select table_name, column_name, ordinal_position
From INFORMATION_SCHEMA.COLUMNS
where table_name = 'TestTable'
TABLE_NAME COLUMN_NAME ORDINAL_POSITION
TestTable myId 1
TestTable Item_# 2
TestTable Count 3
TestTable ProductName 4
TestTable U_Item_# 5
