A/B test an ad with different hooks

[iamzeus]

Have a PHP function for wordpress in my functions.php to display an adsense ad in my posts using a Hook:
genesis_before_loop
Function 1:

    add_action('genesis_before_loop', 'topadd');
    function topadd()
    {
    	if(  is_singular('post') ){
    ?>
       <div class="topadd">
            <div class="wrap">
    <!-- ADSENSE AD1 -->
            </div>
        </div>
    <?php
    	}
    }  

However I want to A/B test this ad in this hook vs this one:
genesis_after_header
Function 2 is:

    add_action('genesis_after_header', 'topadd');
    function topadd()
    {
    	if(  is_singular('post') ){
    ?>
       <div class="topadd">
            <div class="wrap">
    <!-- ADSENSE AD2 -->
            </div>
        </div>
    <?php
    	}
    }  

To A/B/n test inside a php function I use this:

    <?php 
    $option[0] = ' adsense_code_1 ';  
    $option[1] = ' adsense_code_2 ';  
    $option[2] = ' adsense_code_3 ';  
    $option[3] = ' adsense_code_4 ';
    $option[n] = ' adsense_code_n ';
    echo $option[rand()%count($option)];  
    ?>  

But it wont work to rotate functions so what Im looking is:

A code to use in functions.php to rotate/split test my:
Function 1
Function 2
