loads the given score, appending the actual row names from the given DataSet to the rowIDs present in the score. Also, the passed in string is displayed as the score's label (currently displaying the data set's path and the score name).
NOTE: since only the row names an IDs are used from the given DataSet, the actual data should not be passed to this function. A dummy data set with just the rown name-id mappings suffices.
