Looking at the source I see you have a validation limit of 250.
var dnn_ctr1174_ProductList_dlProductDetail_valqty_0 = document.all ? document.all["dnn_ctr1174_ProductList_dlProductDetail_valqty_0"] : document.getElementById("dnn_ctr1174_ProductList_dlProductDetail_valqty_0");
dnn_ctr1174_ProductList_dlProductDetail_valqty_0.controltovalidate = "dnn_ctr1174_ProductList_dlProductDetail_txtqty_0";
dnn_ctr1174_ProductList_dlProductDetail_valqty_0.errormessage = "*";
dnn_ctr1174_ProductList_dlProductDetail_valqty_0.evaluationfunction = "RangeValidatorEvaluateIsValid";
dnn_ctr1174_ProductList_dlProductDetail_valqty_0.maximumvalue = "250";
dnn_ctr1174_ProductList_dlProductDetail_valqty_0.minimumvalue = "1";
I've just check on the demo store and it looks like the validation range is checking for a "string" and hence 3 is greater than 250. I think this is an oversight on my part. It should be checking for a numeric range.
As a work around go into the settings and change "productqty.limit" setting to "999"
