Your question is confusing, do you
mean Database, or the file browser, because the setting you are talking about is a file browser setting.
If you understand the
Database tagnavi syntax, then creating a fomat like:
%format "fmt_title" "%0
3d. %s" tracknum title ? tracknum > "0"
Willl force all track numbers to in zero-padded 3-digit format, and thus automatically sort them...
If it is the File Browser you are talking about, then rename your files to a zero-padded 3-digit format to achieve the same result
