Assuming you want the output to singly escape the semi-colons, thusly:

v=DKIM1\; k=rsa\; t=y\;p=MIGfMA0GCSqGSIb3DQAFG....

you don't need to interpolate anything other than the escape (slash). Try using single quotes in the assignments

my $a = ';';
my $b = "\\" . ';';

"A petty consistency..." would suggest single-quoting a single slash, too, but run with ActiveState (w32), strict and warnings, that fails.

Can't find string terminator "'" anywhere before EOF at 742623.pl line 8.

If you escape the slash (eg: <c>my $b = '\\' . ';';, Perl will not complain.
