Sorting order is wrong

[Lorem Hipster]

Hello,

this is to report that after running the Symbol Organizer to reorder the symbols, there is a bug when numbers are involved.

Example - this is the order after running the plugin:
Navigation / Tabs / 1380
Navigation / Tabs / 360
Navigation / Tabs / 720
Navigation / Tabs / 960

But 'Navigation / Tabs / 1380' should be the last item of the list, not the first.

Thank you!
