The tickets are saved as a custom post type. The ticket status like Open or Close is saved as a custom field. In this custom field the plugin saves only a number. All possible statuses are returned as an array by sts_get_statusArr(). The number is the array index of the status. sts_translate_status() translates this index to the name of the status.
