All three version produce a GET request.

Some searching revealed

The post data specified by PostData is passed as a SAFEARRAY Data Type structure. The VARIANT should be of type VT_ARRAY and point to a SAFEARRAY Data Type. The SAFEARRAY Data Type should be of element type VT_UI1, dimension one, and have an element count equal to the number of bytes of post data.

Armed with that knowledge, I tried 

$IE->Navigate("http://...", undef, undef, [ ord('A'), ord('='), ord('B
+') ]);

Yay! It produced a POST request! Unforunately, the data is kinda weird. I get the following 48 bytes of data (shown in hex). 

03 00 00 00 00 00 00 00
41 00 00 00 00 00 00 00
03 00 00 00 00 00 00 00
3D 00 00 00 00 00 00 00
03 00 00 00 00 00 00 00
42 00 00 00 00 00 00 00

In python, the solution is to use buffer("...post data...") as the argument, but I don't know the Perl equivalent.

This page provides a workaround.

I wish I could solve this (using Win32::OLE::Variant?), but I need to go. I'll try tomorrow. [ Bingo! See my followup for details. ]
