The #u and #s were to be reminiscent of #f and #t.  The idea was to have you

The book is about a mythical language, but that just means that you have to
know how to spell some of the words.  As you will discover, we use lots of
scripts.  One reason was as a reminder.  So, cond^e, which is spelled conde
was to remind the reader about the syntax of Lisp's/Scheme's cond.  It was

kinds of
superscipts (the touching and the ones separated by a space).  In the index,

that end with superscript o (the touching variety, since only run has
