I know lots of people who have disabled automatic Software Update checks
and rely on manual installation to update their system.
The computers are actively used, e.g. for web browsing, so there may be
other ways to detect them.

Mac OS 9 introduced Software Update. There hasn't been anything new on
it for many years, so many people will have turned off the automatic
checking, so they wouldn't be counted as "active" using that methodology
even if they are still using that Mac.
I don't recall offhand whether Mac OS 9's Software Update works in
Classic, but it should.
People running Mac OS X 10.0 through 10.3.9 may have also turned off
automatic Software Update checks as there won't have been anything new
in recent years.
Software Update should at least provide a pretty good sample of a high
proprotion of recent Macs. That can be supplemented with evidence from
elsewhere to estimate the total number of "active" Macs.

Indeed, and it doesn't matter if people running 10.3 and earlier have
turned off automatic checks, because Apple is already not supporting
those systems.

Requiring Leopard doesn't mean it has to be Intel only. It would cut out
G3s, so they could build it to require a G4 processor and always be able
to use the vector unit.
I can't see any justification for a general purpose productivity
application like iWork to require Snow Leopard or an Intel processor,
both of which are mainly speed improvements.
I think Leopard on a G4 is a reasonable minimum requirement for the next
version of iWork. There may be a fair number of Tiger users who would
upgrade to a new version of iWork, but Apple is likely to take the
position that someone who hasn't upgraded their operating system in more
than two years is unlikely to be buying new software, or use it as a
small incentive to encourage an OS upgrade.
iLife has more performance dependent features, but it would be premature
to require Snow Leopard if the next iLife version is released while
Leopard still has a significant market share.
For comparison:
iLife '04 (Jan 2004) requires 10.2 (superseded Oct 2003)
iLife '05 (Jan 2005) requires 10.3 (released Oct 2003)
iLife '06 (Jan 2006) requires 10.3 (superseded Apr 2005)
iLife '08 (Aug 2007) requires 10.4 (released Apr 2005)
iLife '09 (Jan 2009) requires 10.5 (released Sep 2007)
iWork '05 (Jan 2005?) requires 10.3 (released Oct 2003)
iWork '08 (Aug 2007) requires 10.4 (released Apr 2005)
iWork '09 (Jan 2009) requires 10.4 (superseded Sep 2007)
I don't have a copy of iWork '06 but I expect it requires 10.3.
