It appears that the “Order markers by” setting in the Marker Listing options for a map isn’t working correctly when ordered by “Title” for the Carousel mode, if not the others as well. It’s mishandling numbers.

For example, I have:

• Item 1
• Item 2
• Item 3
• Item 3a
• Item 4
• Item 5
• Item 6
• Item 7
• Item 8
• Item 9
• Item 10
• Item 11
• Item 12

as items in my map.

However, ordering the items in the marker list (for the Carousel, at the very least) by Title has the following be output:

• Item 1
• Item 10
• Item 11
• Item 12
• Item 2
• Item 3
• Item 3a
• Item 4
• Item 5
• Item 6
• Item 7
• Item 8
• Item 9

You can clearly see what’s wrong here.

I’m guessing the sort that’s being performed is comparing one character at a time (making the 1 in 1 and 10-12 be next to each other) rather than checking for full/proper alphanumeric sorting (obviously having it count as one would expect.)

It seems like the fix might be to use natcasesort() (https://www.php.net/manual/en/function.natcasesort.php) for this so natural sorting (proper alphanumeric handling instead of “standard” sort() sorting) that’s case-insensitive (I don’t think capitalization should alter the position of an item when sorting by title) is performed.
