Either number your pages with zero-padded numbers like this so ImageMagick takes them in order:

img000.jpg
img001.jpg
img002.jpg
...
img098.jpg

Then your original command should work.

Or, have bash enumerate the files in order and feed the names into ImageMagick like this:

magick img{0..99}.jpg result.pdf

Or:

for file in img{0..99}.jpg; do echo $file; done | magick @- result.pdf

Or rename your files as per the first example above, but using Perl rename:

rename --dry-run 's/\D//g; $_=sprintf("f-%05d.jpg",$_)' f*jpg

Sample Output

'f0.jpg' would be renamed to 'f-00000.jpg'
'f1.jpg' would be renamed to 'f-00001.jpg'
'f10.jpg' would be renamed to 'f-00010.jpg'
'f11.jpg' would be renamed to 'f-00011.jpg'
'f12.jpg' would be renamed to 'f-00012.jpg'

You may have ls -v available to you, in which case you can try:

magick $(ls -v img*jpg) result.pdf
