It seems that any value will work, like mt=0, mt=999, etc.

Answer 1

Apple designates a number of different Media Types (mt values):

1   Music
2   Podcasts
3   Audiobooks
4   TV Shows
5   Music Videos
6   Movies
7   iPod Games
8   Mobile Software Applications
9   Ringtones
10  iTunes U

12  Desktop Apps

So, to answer your question, the "mt=8" in iTunes links simply identifies it as being of type 'Mobile Software Applications'.
