By default, Cfg uses title sort. This means that all articles ('A', 'An' and 'The') are ignored during the sort. If you want a purely alphabetical sort, add:
to config.txt. You can also change the list of words that are ignored by using a comma separated set of words instead of the 0. For example, the default of that option is: sort_ignore = A, An, The
You can also specifically sort your games in order using the pref_game option. The pref_game option allows you to list some games that will always appear at the top of the list. It's format is a comma separated list of 4-character IDs for the games in the order you want them to appear. This doesn't seem to be what you want, though.
Finally, the 'sort' option allows you to use entirely different sort patterns, like number of players, last time played, most often played, release date, etc.
