Besides the ".." typo in the file, which suggests it was never tested, there is this:
result "${partition}:${long}:${label}:reactos" What is the "reactos" in the bootloader type field at the end supposed to do?

Obviously, this should not be added to os-prober until someone has actually tested it. -- see shy jo
