Scala Slick code that does sorting by Enum while assigning different values to be used for sorting

ScalaSlickEnumSortComplex.scala

import scala.language.implicitConversions
object OrderEnum extends Enumeration {
  protected case class Val(actualValue: String, orderValue: String) extends super.Val
  implicit def valueToVal(x: Value): Val = x.asInstanceOf[Val]

  val A = Val("a", "c")
  val B = Val("b", "b")
  val C = Val("c", "a")
}

val q = persons
  .sortBy { i =>
    OrderEnum.values.drop(1)
      .foldLeft(
        Case.If(i.name === OrderEnum.values.head.actualValue)
          .Then(Some(OrderEnum.values.head.orderValue): Rep[Option[String]])
      ) {
        case (acc, enum) =>
          acc.If(i.name === enum.actualValue).Then(Some(enum.orderValue): Rep[Option[String]])
      }
      .Else(Option.empty[String]: Rep[Option[String]])
      .asc
  }

db.run(q.result)
