Iterating through listitems and set number value

Question

Hi,
I have a problem with setting custom number value to list item column.
I first wanted to do it with SPD workflow but it seem to be too tricky.
So lets try with powershell, here's my case:
I want to loop through library items and set value to column "OrderNumber".
Result should be
NAME       PRODUCT    ORDERNUMBER
item             a                        1
item             b                        2
item             c                         3
Here my script so far:
if(!(Get-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction:SilentlyContinue))
    Add-PsSnapin Microsoft.SharePoint.PowerShell
$web = Get-SPWeb http://sharepoint/subsite
$list = $web.Lists["MyListName"]
$listitems = $list.Items.Count
for ($i=0; $i -le $listitems – 1; $i++)
  $item["OrderNumber"] = $i;
  $item.Update();
but this does update only one item....
I presume that i should use foreeach loop, but how to set $i variable in it?
foreach ($item in $list.Items)
  $item["Number"] = Get-Random -Min 0 -Max 100;
  $item.Update();
Thank you for any help!

hi
just do small modification in your code
f(!(Get-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction:SilentlyContinue))
    Add-PsSnapin Microsoft.SharePoint.PowerShell
$web = Get-SPWeb http://sharepoint/subsite
$list = $web.Lists["MyListName"]
$listitems = $list.Items.Count
for ($i=0; $i -le $listitems – 1; $i++)
$item=$listitems[$i];
$item["OrderNumber"]
= $i+1;
 $item.Update();
