Give them time!!  I don't mess about with ziplocks and stuff now, I just
plant them at the right time, cover them with fine gravel and wait.  Some
things germinate within a week (3 year old Dahlia coccinea seed was up in 6
days, and probably every single one of them by the look of it!!  I wasn't
even sure if it would still be viable.... boy was I wrong!!!!) while other
things take ages.  I have had problems with Arum species from J&J Archibald
where some came up immediately (i.e sown in autumn, came up within a month
or so) and others there was not a sign of so I had mentally written them
off as dodgey seed.  2 autumns later some of them are now putting in a
major appearance (Arum dioscoridis var syriacus for example has put up 5 in
the last week or so).  

I've found that Gladiolus for me tend to have a decent germination the
first year, then a lot more follow the following year so I wouldn't be
concerned at the 10% germination at this stage.  I figure that the 12
months in the ziplock may have got them a tad confused and now it'll take
them a while to sort out which season is right, but I don't know the normal
germination techniques for Gladiolus.  I just know that my planting in
autumn as the days start to cool seems to work fine for them, be they
winter or summer growers.  Either way they have a cooler damp winter which
they can choose to germinate immediately for, or wait until the temps warm
up in spring.

Hopefully this is of some help.
