Answer 1

usort with callback will work for you.
usort($array, function($a, $b) {
return $b['count'] - $a['count']; # $a['count'] - $b['count']; will sort asc
});
WORKING DEMO: https://3v4l.org/SUa2F
OR do simple with arsort($array);

Answer 2

Reverse sort by count descending (and name ascending for like counts):
<?php
$items =
[
['count'=>2, 'name' => 'Janitor'],
['count'=>5, 'name' => 'Plumber'],
['count'=>1, 'name' => 'Scrubber'],
['count'=>3, 'name' => 'Winkle Picker'],
['count'=>3, 'name' => 'Window Cleaner']
];
usort($items, function($a, $b) {
$compare = $b['count'] <=> $a['count'];
if($compare == 0)
$compare = $a['name'] <=> $b['name'];
return $compare;
});
var_export($items);
Output:
array (
0 =>
array (
'count' => 5,
'name' => 'Plumber',
),
1 =>
array (
'count' => 3,
'name' => 'Window Cleaner',
),
2 =>
array (
'count' => 3,
'name' => 'Winkle Picker',
),
3 =>
array (
'count' => 2,
'name' => 'Janitor',
),
4 =>
array (
'count' => 1,
'name' => 'Scrubber',
),
)
