selected payment method comparison seems not to work

Hi all

i'm trying with following simplified rule but nothing happens if using maro_credits as payment method!?

{ "rules_pay_with_maro_credits" : {
"LABEL" : "pay with maro credits",
"PLUGIN" : "reaction rule",
"OWNER" : "rules",
"REQUIRES" : [ "rules_conditional", "rules", "commerce_payment", "commerce_pos" ],
"ON" : { "commerce_pos_transaction_completed" : [] },
"DO" : [
{ "CONDITIONAL" : [
{
"IF" : { "commerce_payment_selected_payment_method" : { "commerce_order" : [ "order" ], "method_id" : "maro_credits" } },
"DO" : [ { "drupal_message" : { "message" : "aklfjaipwoejfipasjfijasdfas" } } ]
}
]
},
{ "LOOP" : {
"USING" : { "list" : [ "order:commerce-line-items" ] },
"ITEM" : { "list_item" : "Current list item" },
"DO" : []
}
},
{ "drupal_message" : { "message" : "test pos event" } }
]
}
}

however the orders in admin - store - orders show up with the payment method
