It just had that feel of the type of problem which is constructed as a
programming exercise given to students. It is very common for
students to try to use the net to get help for their assignments. I
have become more cautious.

Please accept my sincere apology.

I cannot personally think of any way to easily accomplish this with
the core set of utilities. But perhaps others on the list will take
it as a challenge to produce a way and to educate both of us.
However, a one line ruby script comes to mind.
ruby -e '$/="delimiter";ARGF.each { |line| puts line.chomp.split(" ").join("\t") }'
This of course can be done similarly with perl.
perl -e '$/="delimiter";for (<>) { chomp; print join("\t",split(" ")),"\n";}'
And even those could almost certainly be simplified further.
