I don't know why exactly, but it has something to do with the fact that
this text is being interpolated multiple times.

You all might want to try adding this line to the file ":MacPerl
Scripts:One Liner/1":

  $line =~ s/\\/\\\\/g;

Add it right after $line is first assigned to.  This will double-backslash
all the backslashes for you.
