It is always a good idea to tell us what operating system and shell you're using when asking questions here. With a standards conforming version of sed, you weren't far off with your sed command:
When I try running that on Mac OS X (which has a BSD version of sed), I get the diagnostic message:
which can be fixed by adding a backslash before the 1st open parenthesis:
but I then get the diagnostic:
The standards only require implementations of BRE parsing code to accept repetition counts up to 255, (and the 358 repetition count in the BRE in the substitute command exceeds that). If we change that to two repetition counts (each less than or equal to 255), it works:
but it can be simplified a little bit to just:
If you want to try this on a Linux system (or another system using the GNU implementation of sed), you might need something like:
but the GNU version might be able to handle the higher repetition count (I don't have a GNU sed to test at this point).

Note that using:
and:
is very dangerous and can produce diagnostic messages or mangled output, and maybe also terminate your awk script instead of producing the output you want if there are any <percent-sign> or <backslash> characters in the input file you are processing. For your own safety, please change the above printf statements in your awk script to something more like:
and:
respectively.
