It's likely that your files aren't properly sorted.  While I didn't
validate your attachments, 'join --help' is explicit that:

Important: FILE1 and FILE2 must be sorted on the join fields.
E.g., use `sort -k 1b,1' if `join' has no options.

Additionally, if you upgrade to coreutils 7.1 (the latest stable version),
join has an option to output a warning if it encounters unsorted input.
