Lightroom imports photos in random order

Just import first, sort and rename later.

Set your Sort: order in the Import dialog wiindow to Capture time. That should place all images in the correct order at the time they were taken. Then do your import with renaming.

Test this before you do another real shoot.

See this post with an explanation and alternate method for selecting the files for proper sort order as selected in the Import module.

Unfortunately, Adobe has never officially documented what the import sequencing should look like. Normally, using a card reader, it seems to be alphabetically within a given folder while the order of the folders may be questionable. Reading the files directly from the camera is a craps shoot for sequencing.

For this reason, using the "import sequence" number is usually discouraged. Using the original file number is usually a better option.
