jquery sort function sorts items as strings instead of numbers

Question

This is my code:

for(var oaa=0; oaa<oacsv.length; oaa++){
    oacsv[oaa]=parseInt(oacsv[oaa]);
}
oacsv=oacsv.sort();

This is my output:

203; 213; 244; 367; 419; 538; 601; 621; 623; 674; 684; 687; 709; 723; 730; 799; 889; 899; 91; 98;

Can you help me?
