How much PHP do you know? You could just calculate the time length between the last login and registration time (if they've never logged in yet), or between the last two logins. If it equals x amount of time, then delete'em. How complicated is your current script? I could probably help you more if you give me more info on how much you know and what kind of script you're working with.
