The limitation of the magic, namely....
The key part is that magical auto-increment is defined earlier as
only working for strings matching "/^[a-zA-Z]*[0-9]*\z/".
Which is described in "Auto-increment and Auto-decrement", though
"Range Operator" does mention.

The range operator (in list context) makes use of the
magical auto-
increment algorithm if the operands are strings.
This would make lawyers happy enough but not (Uni)?coders like
myself. With the advent of Unicode support more people would attempt
things like ("\N{alpha}" .. "\N{omega}") and wonder why it does not
work like ("a".."z"). So we should add something like;

Note that the range operator cannot apply magic beyond C<[a-zA-Z0-9]

use charnames 'greek';
my @greek_small = ("\N{alpha}" .. "\N{omega}");
Does not work. If you want non-ascii ranges, try
my @greek_small = map { chr } ( ord("\N{alpha}") .. ord("\N
{omega}") );
On the other hand, ranges in regexp and C<tr///> works. You may
consider this inconsistent but range operator must accept variables
like <tt>($start .. $end)</tt> while character ranges in regexp is
constant.
