Poking through Adobe, it seems they knew the drop cap codes wouldn't work a year-and-change ago:

I'll look at the drop cap code. It's most likely a bug in the Digital Editions. All of these properties are supported and should work.
Support for justification is optional per W3C CSS spec and support for margin value of auto is optional per IDPF OPS spec. We are planning to implement them at some point, but you can never rely on a reading system to support those.
I'm reasonably sure there's been an update or two since 10/07 to ADE, so, this hasn't been on the priority list.
And, as long as we're at it:

There is no way to turn off page number marks at this point, but it is on our list.
Confession is good:

Some other CSS that doesn't seem to work in Digital Editions are the following:
text-align: justify;
margin-left: auto;
margin-right: auto;
