Can you be more clear on what is actually NOT working? What are the results
you are expecting and what are the results that you get?

Using your example with script files (#1), the output I'm getting is:
################
CommandText ./f2.ps1
IsScript False
UseLocalScope False
################

Using scriptblocks (#2), the output looks like:
################
CommandText param( [string] $p1) "hello world parameter1: $p1 input: $input"

IsScript True
UseLocalScope False
################

However, the following is a completely different approach on solving the
problem of timing asynchronously running tasks. Maybe this can help you with
your problem without raising more questions. ;-)

Note that escaping the scriptblock strings $sb1 and $sb2 is a little bit
weird, but it should be possible to replace this part with external script
files so that the new process will be executed as something like:
"powershell.exe -noprofile -command C:\script1.ps1"
Of course you can also directly specify external applications to be run.

$sb1 = '&{''hello from ''+$pid; 0..10|%{''-'' + $_ + ''-''; sleep 1}}'
$sb2 = '&{''hello from ''+$pid; 0..20|%{''-'' + $_ + ''-''; sleep 1}}'

$externalWindow = $true

$StartInfo1 = new-object System.Diagnostics.ProcessStartInfo
$StartInfo1.FileName = "powershell.exe"
$StartInfo1.Arguments = "-noprofile -command $sb1"
