Custom sorting with a column that contains date and string- Looks like its possible but not sure how

I am working with jquery datatables 1.9 and i have a column that contains a combination of these values. A date, a string 'A' and another string 'B'. When i click on that column i want the column to be sorted with 'A' appearing first then sorted by date and then 'B' appearing next. Is there a way to achieve this functionality?
