Powershell - Within Powershell ISE run multiple line script in Powershell - powershell

Question

I have a script that runs in Powershell ISE but there is a part of that script that has to run in regular Powershell. The script that needs to run in Powershell has multiple lines.
When I try running the script like this:
<#
Some code runs up here
#>
$script = {
$PW = "Password1";
$PW = $PW | ConvertTo-SecureString -AsPlainText -Force;
Add-SQLAssessmentTask -ManagementGroup "SOME_ID_NUMBER" -SQLServerName $env:computername -WorkingDirectory C:\Temp\SQL -ScheduledTaskUsername domain\user -ScheduledTaskPassword $PW -Verbose;
}
$command = $script.ToString()
#Start-Process powershell -argumentlist $command
Start-Process powershell -argumentlist $script
I get the follow error:
When I run the script like this:
<#
Some code runs up here
#>
$arguments = "$PW = ""Password1""","$PW = $PW | ConvertTo-SecureString -AsPlainText -Force","Add-SQLAssessmentTask -ManagementGroup ""SOME_ID_NUMBER"" -SQLServerName $env:computername -WorkingDirectory C:\Temp\SQL -ScheduledTaskUsername domain\user -ScheduledTaskPassword $PW -Verbose"
Start-Process powershell -argumentlist $arguments
I get this error:
If I run each line in regular Powershell, one at a time, it works fine.
Any suggestions?

$Arguments is supposed to be a script block separated by semi-colons if you want to run multiple commands.
$arguments = {"$PW = ""Password1""";"$PW = $PW | ConvertTo-SecureString -AsPlainText -Force";"Add-SQLAssessmentTask -ManagementGroup ""SOME_ID_NUMBER"" -SQLServerName $env:computername -WorkingDirectory C:\Temp\SQL -ScheduledTaskUsername domain\user -ScheduledTaskPassword $PW -Verbose" }
Start-Process powershell -argumentlist $arguments
