[AUDIO] Local Folder Audio Command Not Playing Songs In Folder In Correct Order

### What Red version are you using?

3.5.9

### Cog name

Audio

### Command name

[p]local folder

### What did you expect to happen?

I expected the songs to be queued by alphabetical order, according to the order as listed in the relevant folder, naming convention/song names below:

01 - Nehalennia [Mix Cut] (Original Mix).mp3
02 - The Light [Mix Cut] (Original Mix).mp3
03 - Skylarking [Mix Cut] (Original Mix).mp3
04 - We Are [Mix Cut] (Original Mix).mp3
05 - Lullaby Lonely [Mix Cut] (Progressive Mix).mp3
06 - Made For You [Mix Cut] (Club Mix).mp3
07 - Dream State [Mix Cut] (Original Mix).mp3
08 - Speed Of Sound [Mix Cut] (Album Extended Mix).mp3
09 - Shelter Me [Mix Cut] (Extended Mix).mp3
10 - Lights [Mix Cut] (Club Mix).mp3
11 - Teardrops [Mix Cut] (Original Mix).mp3
12 - Jal¢n [Mix Cut] (Original Mix).mp3
13 - Eterna [Mix Cut] (Original Mix).mp3
14 - Waiting For The Night [Mix Cut] (Beat Service Remix).mp3
15 - Laguna [Mix Cut] (Original Mix).mp3
16 - Jewel [Mix Cut] (Pure Mix).mp3

### What actually happened?

It plays the songs _mostly_ in order. Rather than going 1-16, orders accordingly:

01, 02, 03, 05, 06, 07, 08, 09, 11, 14, 04, 10, 12, 13, 15, 16

### How can we reproduce this error?

1. Call command [p]local folder ..\A State Of Trance Compilations\A State Of Trance 2013 (Mixed by Armin van Buuren)\Disc 1 - On The Beach
2. Bot queues as described in "what actually happened"

### Anything else?

Tried changing leading digits to leading letters and did not change anything.
