The standard Euro Mk4 response is to show the POIs starting with the closest locations - ie: sorted by distance. It is a function of the SF_***.HTM file in the POI data.
This is an HTML file, open with a text or HTML editor and observe the difference between a standard Euro ST file and the USA version.

Look at this line:

<INPUT TYPE="HIDDEN" NAME="SORT" VALUE="CRITERIA+DISTANCE">

You can see that you can specify the sort criteria.

In Europe the SF file requests sorting of POIs starting from the closest locations. Maybe the sorting order is different in the USA. How are your SF files defining the sorting?
