Design name question

[Emperor's Child]

I've noticed that the AI apparently selects new design names from the top of the list. So if you alphabetize your list the AI's appear to just roll down the alphabet as the game continues. I guess I initially assumed that the AI would randomly select names throughtout the game. Why, then, are most of the design names in alphebetized lists? Wouldn't it make sense to jumble up the listst, with good names for small ships on the top of the list and powerful / larger sounding names toward the bottom?
