Query has two syntax, the syntax you are using, last column represents order by, you just need to specify on what column you want to do orderby +"ASC" (or) orderby +"DESC"
Cursor c = scoreDb.query(DATABASE_TABLE, rank, null, null, null, null, yourColumn+" DESC");
The last parameter in db.query() method is the order by clause (without the "order by"). All you need to do is separate both columns by a ",". So it would look like:
Cursor cursor = db.query(TABLE_SESSION, new String[] {KEY_ID, KEY_MODULE_CODE,
KEY_DAY_OF_WEEK, KEY_START_TIME, KEY_DURATION, KEY_SESSION_TYPE, KEY_ROOM},
null, null, null, null, KEY_DAY_ID + " ASC, " + KEY_START_TIME + " ASC");
