array_multisort() not working when I try to sort an multiple array

I have this array $mergeArr: 

  array (size=5)
  'facebook' => 
    array (size=3)
      'facebook_enabled' => string '1' (length=1)
      'facebook_url' => string 'https://www.facebook.com/' (length=25)
      'facebook_order' => string '7' (length=1)   //order element
  'twitter' => 
    array (size=3)
      'twitter_enabled' => string '1' (length=1)
      'twitter_url' => string 'https://www.twitter.com/' (length=24)
      'twitter_order' => string '9' (length=1)   //order element
  'instagram' => 
    array (size=3)
      'instagram_enabled' => string '1' (length=1)
      'instagram_url' => string 'https://www.instagram.com/' (length=26)
      'instagram_order' => string '2' (length=1)  //order element
  'linkedin' => 
    array (size=3)
      'linkedin_enabled' => string '1' (length=1)
      'linkedin_url' => string 'https://www.linkedin.com/' (length=25)
      'linkedin_order' => string '5' (length=1)  //order element
  'pintrest' => 
    array (size=3)
      'pinterest_enabled' => string '1' (length=1)
      'pinterest_url' => string 'https://www.pinterest.com/' (length=26)
      'pinterest_order' => string '3' (length=1)  //order element

I need to sort it according the *_order element in each array.

I tried the code below:

CODE PHP:

array_multisort(array_column($mergeArr, '2'), SORT_ASC, $mergeArr);

Expected output order is: Instagram, Pinterest, Linkedin, Facebook, Twiter.

The error that I receive is the following

array_multisort(): Array sizes are inconsistent

Can you please tell me how can I sort this array so I get what I want?

Thanks in advance!

If the field to compare is always in the 3-th key you can do that with usort and array-values as:

usort($array, function($a, $b) {
    $a = array_values($a);
    $b = array_values($b);
    return $a[2] > $b[2];
});
