Error Values
This method returns S_OK (0x00000000) to indicate success and standard COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object, which can be accessed using the API function GetErrorInfo. In particular, the GetDescription method of the IErrorInfo interface may return a text description of the error.

The Component and Description parameters are optional.
This method assumes that the ContentList object has a column of type CLCOL_R4 with the CLCOL_SCORE_COLUMN flag set.
For the sake of uniformity, pipeline components provided with Commerce Server 2000 pass the Programmatic Identifier (ProgID) of the component for the Component parameter.
