... the tertiary conditional is an if statement(term/expression), wrapped in a do block.

The "tertiary conditional" is a conditional expression: it evaluates to one thing or else another thing. It may produce an effect like that of a  do { ... } block, but I would say it is incorrect to say it is a do-block. (Update: E.g., the  + operator produces a result like that of a do-block with some arithmetic operations in it, but it makes no sense to say it is a do-block.) What does the decompiler say?

Update: Added example. (Update: Changed example to include do-block in list.) 

c:\@Work\Perl\monks>perl -wMstrict -le
"my $x = 1;
 ;;
 my @ra = (
   'x', $x ? 'foo' : 'bar',
   'y', do { if ($x) { 'biz' } else { 'boz' } }
   );
 print qq{@ra};
"
x foo y biz

c:\@Work\Perl\monks>perl -wMstrict -MO=Deparse,-p -le
"my $x = 1;
 ;;
 my @ra = (
   'x', $x ? 'foo' : 'bar',
   'y', do { if ($x) { 'biz' } else { 'boz' } }
   );
 print qq{@ra};
"
BEGIN { $^W = 1; }
BEGIN { $/ = "\n"; $\ = "\n"; }
use strict 'refs';
(my $x = 1);
(my(@ra) = ('x', ($x ? 'foo' : 'bar'), 'y', do {
    if ($x) {
        'biz';
    }
    else {
        'boz';
    }
}));
print("@ra");
-e syntax OK
