A good additional place to read is the man pages.
Under priority this appears:
priority "string"
Default: medium. When there is no tape to write to,
Amanda will do incremental backups in priority order to
the holding disk. The priority may be high(2),
medium(1), low(0) or a number of your choice.
So the difference appears important only when saving ONLY to holding disk.
Then you can define which come earlier or later incase the holding disk
fills.
