For this to work, attrlat and attrlng need to be in lower case otherwise you will get :
"unknown latitude attribute ''"

When sorting on @geodist you have to use SetSortMode with SPH_SORT_EXTENDED, like below, if SPH_SORT_ATTR_ASC does not seem to work.

$sphinx->SetSortMode(SPH_SORT_EXTENDED, '@geodist ASC');
