Another option, when the options get too complex and you're tired of fiddling with quotes, backticks, etc is to use the underused -EncodedCommand parameter on PowerShell.exe e.g.:

C:\PS> $cmd
c:\temp\foo.ps1 'D:\Documents\PowerShell Scripts','D:\SomeFolder'
C:\PS> $bytes = [Text.Encoding]::Unicode.GetBytes($cmd)
C:\PS> $encodedCmd = [Convert]::ToBase64String($bytes)
C:\PS> $encodedCmd

C:\PS> powershell.exe -encodedCommand YwA6AFwAdABlAG0AcABcAGYAbwBvAC4AcABzADEAIAAnAEQAOgBcAEQAbwBjAHUAbQBlAG4AdABzAFwAUABvAHcAZQByAFMAaABlAGwAbAAgAFMAYwByAGkAcAB0AHMAJwAsACcARAA6AFwAUwBvAG0AZQBGAG8AbABkAGUAcgAnAA==
param1[0] is D:\Documents\PowerShell Scripts
param1[1] is D:\SomeFolder

Admittedly, not something that would be exactly readable/understandable by someone else. :-) You'd have to doc the command in the description of the scheduled task.
