Return different output based on input variable

[nitse]

I am trying to write a rule that returns a different output depending on the value of the input.
I have an age range and I want to return different "points" based on user's age. All the examples that I have found have a standard output.
I want to achieve something like the following while avoiding to create a different rule for every age range.:

age output
<55 = +0
55-59 = +1
60-64 = +2
etc

Is it possible?
Thanks !!

As a RulesEngine user, I see the following:

1. a rule just evaluate to true or false (Success or Failure)
2. a rule always expose an ActionResult in its RuleResultTree,
3. if there's no applicable CustomAction defined, the ActionResult will have .Ouput = to rule's RuleResultTree
4. if you define a normal CustomAction that will be like writing static c# code, that's not what you want
5. BUT... there are two special (built in) kind of actions added silently and automatically: the OutputExpression and the EvaluateRule.
   you can use the first one to do what you need, but... at the end you will be creating a rule inside the rule actions

maybe it's better to build several rules matching rule ranges by using an Operator = "OrElse", each rule having the range of interest, but having an OutputExpression CustomAction that returns a Global or Local Param

i.e. (not checked):

GlobalParams (or local, inside the corresponding rule)
AgeRankIrrelevant: someValue
AgeRankConsumer: otherValue
Rules:
Operator: "OrElse"
Rule1:
Expression: "input1.Age <= 10"
CustomActions:
Name: "OutputExpression"
Expression: "AgeRankIrrelevant"
Rule2:
Expression: "input1.Age > 10 && input1.age <= 20"
CustomActions:
Name: "OutputExpression"
Expression: "AgeRankConsumer"
