Wrong lowest price variant

Hello,
I’ve installed the latest version of this plugin 1.61. When I sort the Price from low to high the results are’nt correct.

After reading the code I found that the callback function for usort (hpy_fdv_sortByPrice()) does not return integer.

7.6 - 8.2 = -0.6

as int -0.6 is 0 and interpreted as equal in usort context.

I changed the function hpy_fdv_sortByPrice:

function hpy_fdv_sortByPrice($a, $b) {
    if($a['price'] === $b['price']){
		return 0;
     }
	return $a['price'] < $b['price'] ? -1 : 1;	
   // return $a['price'] - $b['price'];
}

Now, I’ve the expected result. And the plugin works great for me. Hope it helps.

Regards,
Sebastian
