Farhan,
Not knowing much about the traffic or the number of VPNs, a couple of  
things you can try without  the multi-link feature set:

forwarding-options {
     hash-key {
         family inet {
             layer-3;
             layer-4;
         }
         family mpls {
             label-1;
             label-2;
             payload {
                 ip;
             }
         }
     }
}

policy-options {
     policy-statement LOAD-BALANCE {
         term t1 {
             then {
                 load-balance per-packet;
             }
         }
     }
}
routing-options {
     forwarding-table {
         export LOAD-BALANCE;
     }
}

-A
