I'm going to guess the problem is that the js is seeing your object as a
string.
I *think* this would work. Can't say for sure without testing it. I can
never remember weather you can use this.value with a select and have it
work. You may need to change it
to this.options[this.selectedIndex].value.split('|')[0] to target the value.
<select name="location"
onChange="ColdFusion.Map.setCenter('map1',{latitude:this.value.split('|')[0],longitude:this.value.split('|')[1]};ColdFusion.Map.setZoomLevel('map1',10);">
<option>Select Location</option>
<cfloop query="getMapLocations"><option
value="#getMapLocations.latitude#|#getMapLocations.longitude#">#getMapLocations.name#</option></cfloop>
</select>
