Sort array as number but not string in powershell

Question

Would like to convert a string with collection of numbers into a sorted array object in PowerShell. However, it was sorted based on the ASCII value of each character, but not the value of number. For example: I have

[string]$PortException = "3128,53,3389,5985,5986"

When sort with Sort-Object:

$PortExceptionArray = ($PortException.Split(',') | Sort-Object)

The outcome to the array is in the order of:

However, it is expect that "53" will be on the top.

Any thoguht?
