Script Databsae Does Not Compatible With SQL2000

I've
created a databse on SQL2005, and I did not use any new data type for
columns. I script the database, and select SQL2000 for "Script for
Server version", howvever, the script generated cannot be run on
SQL2000, it can be only run on SQL2005.

The script generated by SQL2005 is not backward compatible? like SQL2000 can generated script compatible wtih SQL7.

CREATE TABLE [dbo].[Table1](
[Col1] [nvarchar](16) NOT NULL,
[Col2] [nvarchar](100) NOT NULL,
[Col3] [nvarchar](10) NULL,
[Col4] [datetime] NULL,
[Col5] [nvarchar](10) NULL,
[Col6] [datetime] NULL,
[Col7] [bit] NULL CONSTRAINT [DF_Table1_Col7] DEFAULT ((0)),
[Col8] [bit] NULL CONSTRAINT [DF_Table1_Col8] DEFAULT ((0)),
[Col9] [int] NULL CONSTRAINT [DF_Table1_Col9] DEFAULT ((0)),
CONSTRAINT [PK_Table1] PRIMARY KEY CLUSTERED
(
[Col1] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

Error detected on the line "IGNORE_DUP_KEY = OFF".
