How to set variable with list's metadata (like customerID)?

Question

How do I set a metadata (say CustomerID or Skills) with PowerShell? I am trying to fill CustID. Edited. This is the working version of the final powershell code.

Here is the working code....

$siteURL="http://Server"
$docLib = "My Doc Lib"
$site=Get-SPSite $siteURL
$web=$site.RootWeb
$collFiles=$web.GetFolder($docLib).Files
$count=$collFiles.Count
while($count -ne 0)
{
$item = $collFiles[$count-1].Item
$DocSet = $item["Region"]
Write-Host "$DocSet is the doc set. $collFiles[$count-1].Name is name"
$collFiles[$count-1].MoveTo($siteURL + "/" + $docLib + "/" + $DocSet + "/"  + $collFiles[$count-1].Name, $true)                       
$count--
}
