Elevations in DBPedia

All,

I just wanted to have a few elevations of mountains:

PREFIX pr: <http://dbpedia.org/property/>

select distinct * where 
{
  ?uri a <http://dbpedia.org/ontology/Mountain> ; 
     <http://dbpedia.org/ontology/elevation> ?elev ; 
     pr:name ?name ;
     pr:range <http://dbpedia.org/resource/Hindu_Kush>

}  ORDER BY DESC(?elev) LIMIT 10

try:
http://dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&should-sponge=&query=PREFIX+pr%3A+%3Chttp%3A%2F%2Fdbpedia.org%2Fproperty%2F%3E%0D%0A%0D%0Aselect+distinct+%2A+where+%0D%0A%7B%0D%0A++%3Furi+a+%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2FMountain%3E+%3B+%0D%0A+++++%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2Felevation%3E+%3Felev+%3B+%0D%0A+++++pr%3Aname+%3Fname+%3B%0D%0A+++++pr%3Arange+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FHindu_Kush%3E%0D%0A%0D%0A%7D++ORDER+BY+DESC%28%3Felev%29+LIMIT+10&format=text%2Fhtml&debug=on

What you notice in the result is the different format for the elevation, some 
are 
dbpedia-owl:elevation	"7403"^^dbpedia-owl:metre ;
some are
dbpedia-owl:elevation	"7,349 metres (24,112 feet)" ;

This will cause a mess in the application... Could this be solved when DBPedia 
is compiled some way?

Cheers,

Kjetil
