I am completely new to using string arrays. Consider this example:

I have the following values in a text box:

```
bufallo@2000
lice@20
cell@1
rat@150
cow@10000

```

When I sort them, they are sorted alphabetically, as in the list above. However, I need them to sort in descending order using the integer value that follows the @ symbol. So, for instance, I want the above list to be sorted like this:

```
cow@10000
bufallo@2000
rat@150
lice@20
cell@1

```

I have no idea on how to arrange them in descending order like that.
