that certain characters like & (there may be others) that are between escaped double-quotes be escaped with a ^ (carat).

Yes ... that was the bit of information I was missing.
I had tried using the stick on the on the > and the &, to no avail: 
C:\_32>perl -Mstrict -MDevel::Peek -le "my $arg = \"\>\&STDOUT\"; Dump
+ $arg;"
The system cannot find the path specified.

But using the carrot works fine: 
C:\_32>perl -Mstrict -MDevel::Peek -le "my $arg = \"^>^&STDOUT\"; Dump
+ $arg;"
SV = PV(0x2dcd2c) at 0x1c90564
  REFCNT = 1
  FLAGS = (POK,IsCOW,pPOK)
  PV = 0x1c8ff64 ">&STDOUT"\0
  CUR = 8
  LEN = 10
  COW_REFCNT = 1

Perhaps when the shell saw a backslash in those contexts, it might have been inclined to think "directory separator", so they had to come up with a different escape symbol.

UPDATE: It seems that, even with q()and qq(), there are still times when the carat needs to be invoked as an escape: 
C:\_32>perl -Mstrict -MDevel::Peek -le "my $arg = q(">&STDOUT"); Dump 
+$arg;"
>& was unexpected at this time.

C:\_32>perl -Mstrict -MDevel::Peek -le "my $arg = q("^>^&STDOUT"); Dum
+p $arg;"
SV = PV(0x6bcd2c) at 0x57b30c
  REFCNT = 1
  FLAGS = (POK,IsCOW,pPOK)
  PV = 0x58056c ">&STDOUT"\0
  CUR = 8
  LEN = 10
  COW_REFCNT = 1

C:\_32>perl -Mstrict -MDevel::Peek -le "my $arg = qq(">&STDOUT"); Dump
