I think I'd use `Ordering` trait instead as it's not very easy to spot what
the ordering is.
```
case class Info(id: String)
val infos = Seq(Info("5"), Info("driver"), Info("1"), Info("10"),
Info("500"))
implicit val onString = Ordering[Int].on((s: String) =>
util.Try(s.toInt).getOrElse(-1))
infos.sortBy(_.id)
```
