How can I rearrange product tags in a custom collection by month?

[SeedSloth]

Hello,

I've created a custom themplate for a collection that uses 'Months' as the filter. These have been added as tags within products and the code restricts the filter to only show the Months. What I cant work out is how I change the order so that it's in a set order (i.e. month order) and not just Alphabetical.

Any help would be great.
