Your `score.xml` file is not a valid MusicXML file: It contains stuff
like
```
<duration>4/4</duration>
```
but the `<duration>` element only accepts decimal values (and integers
are preferred according to the MusicXML specification).
It actually looks like this file is what MuseScore uses internally for
storing its data (it starts with a `<museScore>` tag). This doesn't
work with `musicxml2ly`; you have to explicitly *export* to MusicXML.
Maybe you've attached the wrong file to the bug report?
