If you install SSMS 2008, you can use the filter option to filter the list of tables to only those you want and script them.
Or, if you install Powershell and download and install the snap-in for SQL Server, you could do the following:
PS> CD sqlserver:\sql\{server}\{instance}\databases\{database}\tables
PS> Get-ChildItem | % {$_.Script()}
You can expand on the above to filter how you want and output to a separate files as needed.
