There are two ways to get that result. Which works best will depend on the number of such name to number pairings that you need.
a) you can set up a custom value list where you list Dean, Chair, Faculty, Part time faculty... as values in the value list. When sorting these records, you can specify a custom sort order and refer to the value list to get this order.
b) you can use the text to link your records to an index table by the text fields. The index table would have one record for each title and a number field that specifies the order. You can then use sort records to sort your records and specify the number field from the related table.
