Do you have date field? I think it would be the best to work with a date field. In case you don't have one, you can always create it in the script using your month and year fields.

Date(MakeDate(Year, Month, 1)) as Date

Once date is created, use a expression like this:

Sum({<Date= {"$(='>=' & Date(AddMonths(Max(Date), -3)) & '<' & Date(Max(Date)))"}>} Sales)
