If you look at the source to HTML::Element, this would appear to be handled by this line of code:

if ($val !~ m/^[0-9]+$/s) { # quote anything not purely numeric

Altering that will (for a value of "will" equivalent to five minutes poking at source code and not doing any testing whatsoever) allow you to quote any value. I might look into writing a patch and submitting it to the author at some stage.
