How does the term typology apply or describe the use of Romans 13:13 ("Not in rioting and drinkenness...") by St Augustine in his conversion scene book VIII of his Confessions?
Typology explores the relationships between the Old and New Testament and how the New Testament represents a fulfilling of the Old Testament in terms of the promises and various covenants that God makes with man. The verse this question refers to seeks to explicitly link the Old and New Testament in this way by seeing Jesus as a natural outcome and fulfilling of Old Testament promises.

Basically, "Confessions" includes a personal history, and includes a very personal reflection on God, humanity, and human history. Thus the book is almost as personal as it is as religious text. It describes one man's personal journey to God.
"Typology" refers to the habit of reading the Old Testament as foreshadowing the New Testament. Thus, Adam in the Old Testament foreshadows Christ in the new; the Tree in the Old Testament foreshadows the Cross in the New; Mary in the Old Testament foreshadows Eve in the New; the story of Abraham and Issac in the Old Testament foreshadows the actual crucifixion in the New, and so on.
The passage from Augustine to which you refer has been interpreted in similar ways. Here is one example:
