It's not a lie. the scalar is indeed a PVNV.

SV = PVNV(0x83929d8) at 0x83ae2d8
  REFCNT = 1
  FLAGS = (PADMY,pIOK)
  IV = 2
  NV = 0
  PV = 0

The scalar type simply indicates what type of data the scalar *can* hold. It
doesn't indicate what kinds of data it *does* hold.

How this has escaped causing serious malfunction I don't know

Why would it malfunction? Are you saying that

$_=1.1; $_=1;

should also malfunction because it returns a PVNV without NOK?

$ perl -MDevel::Peek -e'$_=1.1; $_=1; Dump($_);'
SV = PVNV(0x9a939b0) at 0x9abeec0
  REFCNT = 1
  FLAGS = (IOK,pIOK)
  IV = 1
  NV = 1.1
  PV = 0
