No, you can not use "$a > 0 AND $a < 10" as a logical operation in Windows PowerShell scripts. You must use PowerShell logical operators given below:

 -and    Logical AND
 -or     Logical OR
 -not    Logical NOT
  !      Logical NOT

Here are some examples of how to use PowerShell comparisonoperators:

$a = 2
$b = 3
"Is a < b and b < 10? "+($a -lt $b -and $b -lt 10)
"Is a < b or b < 10? "+($a -lt $b -or $b -lt 10)
"Is a not < b? "+(-not $a -le $b)
"Is a not < b? "+(! $a -le $b)
