Why not use the birtdatetime functions available in the expression
builder to add a computed column for week (1-52) and group on that?
Look at the two computed columns in the attached report.

You can always create a computed column using a Java util calendar like:
importPackage(Packages.java.util);
cl = new GregorianCalendar();
cl.setTime(row["ORDERDATE"]);
cl.setFirstDayOfWeek(Calendar.MONDAY);
cl.get(Calendar.WEEK_OF_YEAR);
You can set the first day of the week to whatever you want then drag the
dataset onto the report, group by week and put an aggregation element in
the group footer. Select the detail row and delete it.
