In the Test vector "D.2.3. Hash to Scalar Test Vectors"
the dst is "4242535f424c53313233383147315f584d443a5348412d3235365f535357555f524f5f4832475f484d32535f4832535f"
in your own files the used dst is as follows:
"4242535f424c53313233383147315f584d443a5348412d3235365f535357555f524f5f4832475f484d32535f4d41505f4d53475f544f5f5343414c41525f41535f484153485f"
