You can edit Parameter-2 value 0.0 to 180.0 like below
(function (){
var actionCode = "/version 3 /name [ 4 73657431]"
+ "/isOpen 1 /actionCount 1"
+ "/action-1 {/name [ 7 616374696f6e31]"
+ "/keyIndex 0 /colorIndex 0 /isOpen 1"
+ "/eventCount 1"
+ "/event-1 {/useRulersIn1stQuadrant 0 /internalName (ai_plugin_simplify)"
+ "/isOpen 0 /isOn 1 /hasDialog 1 /showDialog 0 /parameterCount 4"
+ "/parameter-1 {"
+ "/key 1919182693 /showInPalette 4294967295"
+ "/type (unit real) /value 100.0 /unit 592474723}"
+ "/parameter-2 {"
+ "/key 1634561652 /showInPalette 4294967295 /type (unit real) /value 180.0 /unit 591490663}"
+ "/parameter-3 {"
+ "/key 1936553064 /showInPalette 4294967295 /type (boolean) /value 0}"
+ "/parameter-4 {"
+ "/key 1936552044 /showInPalette 4294967295 /type (boolean) /value 0}}}";
var tmp = File(Folder.desktop + "/tmpSet1.aia");
tmp.open('w');
tmp.write(actionCode);
tmp.close();
app.loadAction(tmp);
app.doScript("action1", "set1", false);
//app.unloadAction("set1","");
tmp.remove();
}());
Its work fine in my environment.
