We do some similar date comparisons for a coupon add-on that we have
implemented for a few of our clients.

The way that we do it is to store the dates in the database in this
format:
YMD

For instance, February 27, 2003 would be stored as:
20030227

You can get that value in IC by using:
[convert-date fmt="%Y%m%d"][data-session time][/convert-date]

Then, we run similar "if" statements as the one you mentioned above by
assigning scratch variables to the two dates to be compared.

For instance, you can set a scratch variable of today's date with
something like:

[tmp today_date][convert-date fmt="%Y%m%d"][data-session
time][/convert-date][/tmp]

You can then set another scratch variable with the date from the
database in a number of ways. We use a query like this:

[query sql="select start_date, end_date from coupons where coupon_code =
'[scratch coupon_entered]'" list=1]

[tmp coupon_date][sql-param start_date][/tmp]

[/query]

Finally, you can run an "if" statement comparing the two scratch
variables created above with something like this:

[if type="scratch" term="today_date" op=">" compare="[scratch
coupon_date]"]
foo
[else]
bar
[/else]
[/if]

Hope this helps get you started.
