PHP 5.2 error when updating 2.1.x to 2.2.2

Very nice plugin…
Site is not live, still working with it. I have a copy on my local computer and on the remote server. I updated on my local box without any errors. On the remote server I get a white page with this:

Parse error: syntax error, unexpected T_FUNCTION in /home/…../wp-content/plugins/easy-property-listings/lib/shortcodes/shortcode-listing.php on line 88

This is line 88
[code]
`add_filter('epl_sorting_options',function($sorters) {
foreach($sorters as $key => &$sorter) {
if($sorter['id'] == 'status_asc' || $sorter['id'] == 'status_desc') {
unset($sorters[$key]);
}
}
return $sorters;
});
[/code]

I reverted and updated again with the same result. I suspect this is due to an older version of php. The remote server is using 5.2.17. My local server has 5.4.41.
I wanted to be sure I was correct before I see if I can get the ISP to update php.

Thanks for any information you can provide.
