Duh...

Remember me having some issues with Custom Objects not beeing ordered in PoSH v2?

$propertyOfSven = @{}
$propertyOfSven.first = "Sven"
$propertyOfSven.last = "Karlsson"
$propertyOfSven.phone = "040-11 12 13"

> $propertyOfSven

Name                           Value
----                           -----
last                           Karlsson
phone                          040-11 12 13
first                          Sven

> $sven = New-Object PSObject -Property $propertyOfSven

> $sven

last                      phone                       first
----                      -----                       -----
Karlsson                  040-11 12 13                Sven

Well, why don't we just Sort the object output (thanks to Bill Stewart)?

> $sven = New-Object PSObject -Property $propertyOfSven | Select-Object first,last,phone

> $sven

first                   last                           phone
-----                   ----                           -----
Sven                    Karlsson                       040-11 12 13

And done.
