You can try this piece of code:

usort($data,function($a,$b){
    return strcmp($a['sys_title'],$b['sys_title']);
});

print_r($data);

Suppose your array name is $a then:

$tmp = Array();
foreach($a as &$ma) {
    $tmp[] = &$ma["sys_title"];
    array_multisort($tmp, $a);
}

Result will be

Array
(
    [0] => Array
        (
            [sys_id] => 8
            [sys_title] => Bakery Ordering System
            [sys_home] => /cp/system/bos/
        )

    [1] => Array
        (
            [sys_id] => 9
            [sys_title] => Checklist
            [sys_home] => /cp/system/chl/
        )

)
