I'm setting up a template like this. However the order in the admin does not correspond to these numbers. I've refreshed the front end page and the admin.

Has the way you set the order changed?

<cms:template title='Mission' >
<cms:editable order='10' name='article_heading' label='Article Heading' type='text' />
<cms:editable order='20' name='article' label='Main Content' type='richtext' />
<cms:editable order='900' name='page_title' label='SEO Page Title Tag' type='text' />
<cms:editable order='910' name='page_description' label='SEO Page Description Tag' type='text' />
