In your script:

OrderCtrl = function ($scope) {



    $scope.deliveries = [{
        name: "RussianPOST",
        tax: [{
            town: "Moscow",
            price: 10,
        }, {
            town: "Izhevsk",
            price: 30,
        }]

    }, {
        name: "DHL",
        tax: [{
            town: "Moscow",
            price: 50,
        }, {
            town: "Izhevsk",
            price: 100,
        }]
    }

    ];


    $scope.selectedDelivery = $scope.deliveries[0];
    $scope.TaxSelect=function(tax){
        $scope.selectedTax = tax; 
    }
}

Your option (I am not sure if ng-model is needed here, but i am letting it stay):

<option ng-repeat="tax in delivery.tax" ng-value="tax" ng-model="$parent.selectedTax" ng-click="TaxSelect(tax)">{{tax.town}} {{tax.price}} $</option>

Your display:

Tax delivery: {{ selectedTax.town}}, {{ selectedTax.price}}
