Fixed the length of bundle_key to 3-digit

[Problem]
 Playlist is sorted to 1 - 10 - 11 - ... - 2 - 3(character sorting),
 but wanted to be sorted like 1 - 2 - 3 - ... - 10 - 11.
[Cause]
 The bundle_key is character, the length of bundle_key doesn't affects sorting.
[Solution]
 Fixed the length of bundle_key to 3-digit(3-character).
