I have a couple of Wright chokes for my BT-99,does the higher the number mean tighter the constriction? The tubes are marked 7,8,9.

The numbers are X 4/1000 constriction, so a 7 would be 28/1000, etc.

Wright's web site - wrightsgunsmiths.com - has a choke tube page. Go to that page, mash on Browning Invector (or any other gun maker), and you'll get a chart listing the details.
