It's explained in the section of the PEP titled "Why $ and Braces?".
I quote that section entirely: """The BDFL said it best: The $ means "substitution" in so many languages besides Perl that I wonder where you've been. [...] We're copying this from the shell."""
That states that the $-substitution is common in other languages, and was copied from the shell. It does not provide a case for the merits of $ substitution (as opposed to using other delimiters), nor a rationale why copying from another language is a good idea in this instance.
