How to sort in descending or ascending order in getPage?

Question

MODX

Sorting alphabetically works with &sortby=`{"pagetitle":"ASC"}`, but not by number.

[[!getPage?
            &elementClass=`modSnippet`
            &element=`getResources`
            &limit=`18`
            &showHidden=`1`
            &tpl=`tovar`        
            &includeTVs=`image-tovar,old-price-tovar,price-tovar`
            &where=`{"template":6}`
---------
            &sortbyTV=`price-tovar`
            &sortbyTVType=`integer`
            &sortdirTV=`DESC`
---------
            &parents=`2`
            &includeContent=`1`
            &hideContainers=`1`
        ]]
