The link I sent you earlier shows two loops.
The outer loop goes through one feature collection (in this case the points you
want to check). You may have to reproject them to match up with your shapefile
as per the email with andrea.
The inner loop is done using a query against your shapefile. You construct the
query using your point. The result is a feature collection (perhaps empty!) of
the polygon(s) that contain the point.
You may want to adjust the query so that it says "contains" rather than
intersects.
