Combining proximity_fetch and order("-modified") is not working here

[GoogleCodeExporter]

What steps will reproduce the problem?
a = A.proximity_fetch(A.all().filter("modified ",
 timeline).filter("published =", True).filter("modified <=",
 bookmark ).order("-modified") ,db.GeoPt(lat, lon),max_results=PAGESIZE
 +1, max_distance=m)

What is the expected output? What do you see instead?
order("-modified") should sort by time. Results come out seemingly random 
sorted.

What version of the product are you using? On what operating system?
Google App Engine production server + geomodel 

Please provide any additional information below.
I'm trying to order by date using db.GeoPt to store google maps coordinates 
with GAE and geomodel I can map and match Sao Paulo and can't sort by time

A workaround now enabled the wanted effect using lambda sorting. Thanks for a 
great software.
