The regex is not recognizing the sprintf as a function in the second part of the s/// operator, so it's probably better (and more legit) to break this into two lines: 
if ($url_text =~ m/([^;\/?:@&=+\$,A-Za-z0-9\-_.!~*'()])/ )
{
  $url_sub = sprintf( "%%%02X", ord( $1 ) );
  $url_text =~ s/([^;\/?:@&=+\$,A-Za-z0-9\-_.!~*'()])/$url_sub/;
}

Update Or , duh, use the s///e modifier (stupid me...) 

$url_text =~ s/([^;\/?:@&=+\$,A-Za-z0-9\-_.!~*'()])/sprintf( "%%%02X",
+ ord( $1 ) )/ge;
