Here is the code I did in Pathfinder for Wayfinder#1. The choice was either for the Scimitar, Cleric Channel Energy, or Skill Knowledge Relgion.

The chooser was:

<fieldval field="usrCandid1" value="thingid.wScimitar|thingid.cClrChan|thingid.skKnowRel"/>

The Eval script looked like this which should be what you are looking for.

~Pre-Levels 5,000
~ If we've not chosen anything, get out
doneif (field[usrChosen1].ischosen = 0)

~If scimitar selected make the character proficient
if (field[usrChosen1].chosen.pulltags[thingid.wScimitar] = 1) then
      foreach pick in hero where "IsWeapon.wScimitar"
        perform eachpick.assign[Broadcast.WepProf]
      nexteach
endif
~If Know(Religion) selected make it a class skill
if (field[usrChosen1].chosen.pulltags[thingid.skKnowRel] = 1) then
   #makeclassskill[skKnowRel]
endif
~If Channel Energy selected give it a +1 to the DC
if (field[usrChosen1].chosen.pulltags[thingid.cClrChan] = 1) then
      #dc[xChannel] += 1
      ~also add to the DC of our help
      #dc[fComUnHelp] += 1
      #dc[fTurUnHelp] += 1
endif

The thing is to do the pulltags[] function.
