Perhaps try the script beforehand in a terminal:
----  snip  ----
{2}sed -e '|x|y|'
sed: -e expression #1, char 1: unknown command: `|'
----  snip  ----
So no, it's not.

You actually wanted:
----  snip  ----
echo $1 | sed -e 's|</head>|<style>* {color:white !important; background-color: black !important; } </style></head>|'
----  snip  ----

Or just use bash (and avoid anorther fork()+exec()):
----  snip  ----
#!/bin/bash --norc
echo ${1/<\/head>/<style>* {color:white !important; background-color: black !important; } <\/style><\/head>}'
----  snip  ----
Caveat emptor: Untested!

I know all that stuff about sed (GNU-sed and other sed's ..) ...
